For example, there's absolutely nothing stopping Al Aly from using a real, consistent control (e.g. influenza, or even just the same negative control) instead of a grab-bag of different illnesses. The reason he switches them with every paper is probably because his synthetic weighting scheme produces inconvenient results from experiment to experiment when the same control is used. But we can only speculate, because we don't have the data. Remember: he's re-weighting his covariates using these controls! This is a real, objective problem.

My opinions about Topol are my own, which is why I said they're editorial, but I'm tired of the guy's constant doom-and-gloom messaging and inability/unwillingness to critically appraise data. Even in the most charitable, rational take on Al Aly's work, you can't casually extrapolate it to the entire population the way that Topol does.

Lazy? Guilty as charged.
