https://academic.oup.com/aje/article/185/3/203/2915143 The study seems pretty sound and they did a multivariate regression for inference too. What is your concern? Confounding factors? Lack of calibration? > This study design also cannot show causation, just correlation. The control group is self selecting Sure but then again, causation models are currently barely picking up steam in term of being studied and more of a PhD academia study right now. All you have are statistical inference models that we've been using for most research papers that are doing inference. While a statistician is going to word conclusion carefully, at the end of the day, somebody is going to have the paint a picture and make some plausible leap. And then other researchers can build upon the paper and redo it with better data set or a different inference models. |
