Chapter 389 Top Journals (First Update)
After collecting the last data, Lu Chen returned to the dormitory.

The procedure of clinical scientific research is simple, collecting data, processing and analyzing data, drawing conclusions, and finally writing a paper.

Currently, Lu Chen has only completed the first step.

But this first step, and the most important step, takes up more than 50% of the overall workload.

"Ke Yue, thank you and your roommate for your help during this time." Lu Chen sent Ke Yue a WeChat message.

Ke Yue replied immediately: "If you have anything to do with the thesis, please tell me, I can help."

"Ok."

However, Ke Yue's help is not needed for the next thing.

To process and analyze data, the main use is SPSS software, and Lu Chen can handle it by himself.

……

In the next week, Lu Chen focused more on data processing.

On weekends, Lu Chen stayed in the dormitory as usual,
"Lu Chen, I heard that there is a very good person in your cardiology department." Zhou Wei, who was moving bricks in the laboratory, sent him a WeChat message, "I sent a new SCI article as soon as I was in research!"

"Well, it's still from the eighth district in our hearts." Lu Chen replied, "Why, want to know? I can introduce you."

"Hey, forget it." Zhou Wei said, "Let me tell you, my latest paper has also been accepted! Although it's not the first paper, the score is not bad, with 3 points!"

"You're not bad, boy." Lu Chen praised.

A paper can have many authors.

Usually, however, only the corresponding and first authors are admitted.

The corresponding author, usually a mentor, is the proposer of the idea of ​​the article.

The first author is the main experimenter, or the author of the paper.

The remaining second, third, and fourth authors all contributed to the paper, such as Ke Yue, who helped process data and so on.

Generally speaking, any evaluation, evaluation, and promotion of positions will only recognize the papers of the corresponding author and the first author.

However, if an SCI paper has a high score, such as Nature, Science, etc., and the impact factor score is above [-]%, as long as you leave your name among the authors of the paper, no matter how many authors it is, then you can almost be listed in a third-rate paper. university professor.

"Oh, I did this experiment with my senior brother." Zhou Weidao, "So the mentor is the communication, and the senior brother is the first author, who gave me a second author. The idea for the next experiment is my own. If I can make it, it will definitely It's just a one-off!"

"Then I'll wait for your good news." Lu Chen said.

"You too, let's encourage each other." Zhou Wei said.

Everyone around is working hard!

Lu Chen closed WeChat and continued to process the data in hand.

His data processing, under the blessing of clinical scientific research skills card and statistical skills card, used multiple statistical methods.

These include Kaplan-Meier method, Log-rank method, multivariate COX regression analysis and so on.

Using a variety of statistical methods to process the experimental data repeatedly, the final conclusions can be more convincing!

When Wang Zihao passed by Lu Chen, he accidentally caught a glimpse of his computer screen and was almost stunned.

The arithmetic symbols on the screen dazzled him.

"Lu Chen, how many statistical methods did you use?" Wang Zihao couldn't help asking.

"Not many, just five." Lu Chen said, "First use the Chi-square test and Fisher's exact probability method for comparison, then use the Kaplan-Meier method to analyze, then apply the Log-rank method to calculate whether there is a statistical difference, and finally use the multiple Variable COX regression analysis confirmed my conclusions."

Wang Zihao: "..."

Damn Versailles!

He only used a chi-square test, and Lu Chen actually used so many methods.

The gap is really quite big...

"Lu Chen, you did the statistics by yourself? Didn't you ask a student majoring in statistics to help you?" Wang Zihao suddenly thought of this.

Statistics is a brand new profession!
Where did Lu Chen find so much energy to learn statistics?

"Well, it's better to rely on ourselves. It's impossible to rely on others to help us count the data every time, right?" Lu Chen smiled.

"You are awesome!" Wang Zihao extended a thumbs up to Lu Chen.

Let him learn this, he thinks he doesn't have the patience and ability.

Seeing Lu Chen's concentration, Wang Zihao sighed a little.

Lu Chen's current achievements are inseparable from his hard work!

He has never seen it so far, Lu Chen went out to play during the weekend break.

This can also explain why his sister Wang Ruoxi has a good impression of Lu Chen.

However, Lu Chen, a straight man, is puzzled.

Wang Zihao felt a little pity and heaved a sigh of relief.

It's a pity that it's because Lu Chen is really a nice person. After getting along with him for so long, he is definitely a reliable man.

He breathed a sigh of relief, because if they got married, wouldn't Lu Chen become his brother-in-law?
Meet every day, but still have to call "brother-in-law"?
……

Lu Chen didn't know that Wang Zihao behind him was thinking about his own affairs in a mess.

He is still busy with data processing.

Now comes the final step of data processing!
That is to say, it depends on whether the conclusions drawn are statistically significant!
"This last step, we will see the outcome!"

Lu Chen was a little nervous.

If there is no statistical significance, then his hard work in the past few months will be in vain!
Therefore, some experimenters often change the data in order to obtain a positive result if they do not obtain satisfactory results in this last step.

This is also a very common phenomenon in China.

Especially some hospitals in China.

Blindly pursuing papers, ignoring that many doctors have no scientific research ability at all, so what should we do?

Only buying papers, data falsification, or even plagiarism!
This is very realistic and very sad...

"Beep beep..."

The computer was running, and several unknown characters flashed continuously.

Finally, after waiting for 5 minutes, the computer screen output the final result
P<0.05——statistically significant!
That is to say, in a small-sample experimental study, Daxigliflozin can prevent heart failure in the early stage of acute myocardial infarction, and this proposition is established.

Lu Chen showed joy and sighed, "Five months, it's finally finished!" "

Others have published several core journal papers in five months.

And he is still Zero Egg!

……

Once the data has been processed, all that remains is to write the paper.

Thesis writing, step by step.

With data and conclusions, it is much simpler.

Lu Chen first finished writing the thesis in Huaxia, and then translated Huaxia into English.

If you want to publish high-scoring SCI papers, Chinese journals do not have such influence for the time being, only foreign journals can.

Even the most authoritative Chinese periodical series in China has limited international influence.

This is also a very helpless reality!
The four top journals in the medical field are all abroad.

They are NEJM (New England Journal of Medicine), The Lancet (Lancet Magazine), JAMA (American Journal of Medicine), and The BMJ (British Journal of Medicine).

Lu Chen definitely doesn't dare to expect these four top journals now, but he must also find a more influential foreign journal for his first paper.

However, Lu Chen didn't know much about the market of foreign journals, so he asked Senior Sister Sun Guoguo.

Senior sister Sun Guoguo has worked hard in scientific research for many years, and she is very familiar with journals in the cardiovascular field.

She immediately gave Lu Chen three suggestions.

"Cardiology Clinics, Cardiology, Pediatric Cardiology."

Lu Chen searched for relevant journal information.

The impact factors are all 1-2 points, no more than 3 points.

Lu Chen frowned, this did not meet his expectations!
