Chen Cang chose this topic for a reason!
In fact, the choice between "cardiac arrest technique" and "non-arrest cardiac surgery" ultimately depends on the patient's own situation.
Using conventional clinical trial control and experimental groups is a very inappropriate experimental method.
What does real-world research mean?
Simply put, it means that patients choose their treatment based on their actual situation, truly reflecting clinical choices in the real world, rather than being divided into treatment groups, control groups, placebo groups, etc. like in clinical trials...
Therefore, real-world research is the most fitting and satisfying to the actual clinical situation.
However... it's the hardest in terms of computation, probability, and other aspects!
Also, the sample size required is quite large, so generally, very few people carry out such research.
Currently, not many are performing non-arrest cardiac surgeries, making similar research even more difficult.
