Earlier you were saying how you didn't trust only observational studies and wanted to see people actually doing randomized trials. That was for a meta-analysis, but this neither a meta-analysis nor an RCT. It is a single purely observational study. Further, looking at their 95% confidence interval graphs... you can see the many of trends could potentially be completely reversed and still within the 95% confidence interval. Their 95% confidence interval contain probable outcomes where 140mg/dL was the worst possible level as well Further it also still finds increased risk for heart issues with higher LDL. > Any increase in LDL-C levels was associated with an increased risk of myocardial infarction.
