********CRITIQUES, RULES, AND NOTES********

Be aware of the following rules before posting comments:
- Please do not post summaries of the video in the comments - it damages retention on the video and YouTube is less likely to promote it (these videos cost me a lot of money to produce).

Critiques of my work are welcome! Please be aware of the following notes & rules before submitting critique:

Be mindful that this content is not all encompassing on the subject at hand and is self-limited for brevity to reach a wider audience. Also, be aware that I receive hundreds of YouTube comments per day, so the only way your critique can be considered is if you follow the steps outlined below. Finally, YouTube auto-deletes links, so I do not see most comments with links attached.

RULES:
If your comment is rude, you will be banned.
If your comment is not about the studies/topics at hand (i.e. extending to other outcomes not discussed) or offers critique with no scientific basis, it is unlikely to receive a response.

If you can follow these rules, I will try to address your critique and if there is merit, I will add an AMENDMENT to the content in question and pin it so everyone can see it (thank you!).

Mindsip insights from this episode:

Recognize long-term risks from short-term studies

A small absolute risk found in a short-term study can be misleading because that risk tends to balloon into a life-threatening one as time passes.

Recognize early trial termination as ethical due to profound positive effects

A clinical trial may be stopped early by an ethics board not due to bias, but because the positive effect is so profound it would be unethical to continue.

Understand why treatments reduce events but not mortality

A treatment can reduce cardiovascular events like heart attacks but not deaths because many more people have events than die, giving the 'event' data more statistical power.

Stay updated on blood pressure target research for evolving insights

The Cochrane Review questioning lower blood pressure targets is not the final word, as newer and ongoing trials already suggest the final verdict may change.

Understand three levers to detect treatment effects in research

The ability to detect a treatment's effect depends on three levers: the trial's duration, the size of the effect, and the number of participants.

Avoid conclusions from barely significant data

You should not make groundbreaking conclusions from data that barely misses statistical significance, as the researchers themselves may state the results are not conclusive.
