In other words this study used zero direct observational studies.
No one has ever fed one person a meat diet and another person meat free diet and shown there to be a increase or decreased risk of heart disease.
Daily reminder that Hong Kong has one of the highest meat consumption per person in the world And one of the highest life expectancies.
India has some of the lowest meat consumptions in the world and one of the lowest life expectancies.
So clearly meat is not the demon some of these biased studies make it out to be.
From another meta analysis which talks about this more directly:
>Nevertheless, several RCTs have examined the effect of vegetarian diets on intermediate risk factors of cardiovascular diseases (Table 1). In a meta-analysis of RCTs, Wang et al. (22) found vegetarian diets to significantly lower blood concentrations of total, LDL, HDL, and non-HDL cholesterol relative to a range of omnivorous control diets. Other meta-analyses have found vegetarian diets to lower blood pressure, enhance weight loss, and improve glycemic control to greater extent than omnivorous comparison diets (23-25). Taken together, the beneficial effects of such diets on established proximal determinants of cardiovascular diseases found in RCTs, and their inverse associations with hard cardiovascular endpoints found in prospective cohort studies provide strong support for the adoption of healthful plant-based diets for cardiovascular disease prevention

India and Hong Kong have very different levels of income. Comparing the two is rather misleading when that's going to affect things like access to healthcare

A high ldl over the age of 60 is associated with a lower all cause mortality.
And you are kinda right, having a higher income means you can afford more red meat and live longer.
