How it does not? The fact is that a significant percentage of people (if I remember correctly, around 41%) having a heart attack also have low blood pressure. If the relationship is causal (and it is hard to imagine it is not), that means that, had those people eaten something that increases blood pressure (such as salt), maybe they wouldn't have gotten a heart attack, right?

OK, I'll weigh in here. When was the BP measured? Was it clinically diagnosed prior to the patient's admission for a heart attack? Just maybe heart failure results in lower BP during admission to the hospital for said condition? Maybe some of them flat-lined. Guaranteed to give a low blood pressure reading. How much med school have you been through? What makes you actually competent, other than some hearsay that you read? You come here asking for programming help, and you claim to be a programmer. Do you get the gist of what I'm saying, here?

Is that how you think scientists determine the cause of some effect? They just try to imagine if it’s not?

Just stop. You’re embarrassing yourself.

YOU made that claim, YOU back it up.

And, if I show you my source, you will then complain it is a libertarian think-tank arguing against government telling us what to eat, right?

I think I can safely promise you that that will NOT be my complaint.

Research....Google.

No, I think they determine the cause and effect using the p-values. I think the p-value can be estimated analitically here, but I am not willing to spend time relearning statistics just for this, so I am going to estimate it numerically using this JavaScript program (just like I numerically estimated the p-value in the latest linguistics paper I have published):
That program prints:
Since the p-value is less than 5%, we conclude the relationship is causal.

What does "complaint" mean?

Well, that's actually a pretty smart idea. I haven't thought of that.

I think the p-value can be estimated analitically here, but I am not willing to spend time relearning statistics just for this, so I am going to estimate it numerically using this JavaScript program (just like I numerically estimated the p-value in the latest linguistics paper I have published):

Code:

const how_many_people_in_the_general_population_have_low_blood_pressure=1/3; // I think it's even less than that, but let's go with that.
const how_many_people_with_heart_attacks_have_low_blood_pressure=0.41;
const how_many_people_were_in_the_study=100; // And I am quite sure there were more, but let's go with that.
const how_many_times_will_we_run_the_simulation=10_000;
let how_many_times_did_we_get_the_expected_result=0;
for (let i=0; i<how_many_times_will_we_run_the_simulation; i++) {
  let counter=0;
  for (let i=0; i<how_many_people_were_in_the_study; i++)
    counter+=Math.random()<how_many_people_in_the_general_population_have_low_blood_pressure;
  if (counter/how_many_people_were_in_the_study>how_many_people_with_heart_attacks_have_low_blood_pressure)
    how_many_times_did_we_get_the_expected_result++;
}
console.log(`The p-value is ${how_many_times_did_we_get_the_expected_result/how_many_times_will_we_run_the_simulation*100}%.`);

That program prints:

Code:

The p-value is 4.32%.

Since the p-value is less than 5%, we conclude the relationship is causal.

Lol, wait. What data did you feed into that thing? Show your work. Also, P values don’t definitively prove cause and effect.

Wow.  Look at that.  A for loop.  Such science.

An instance of complaining. In other words, if I complain about your source, it will not be for the reasons you mentioned.
