Reply to comment by goosegirl86 in The study concluded that post-COVID-19 syndrome was detected in 25% of the included participants. COVID-19 hospitalization, initial symptomatic COVID-19, and female sex were significant risk factors for developing post-COVID-19 syndrome. by bo_hossuin_14

Bingo! Premenopausal women (higher estrogen levels than post menopausal) who are taking hormonal birth control are at much higher risk of clotting events. The study in this post was conducted mainly in Saudi Arabia, where rates of normal birth control usage are much lower than the US. From a quick control F, they didn’t control for birth control. If not controlled for, I imagine the association between female sex and long COVID would be stronger in the US. I don’t think birth control is a confounded though, as women at baseline have higher risk of blood clots.
