The whole pattern dimension included 1.3 million individuals, however the workforce identified that solely 35 of 640,634 articles supplied information by intercourse and sufficient particulars about scientific signs and end result to make a gender comparability.
All the 35 research had been performed earlier than COVID-19 vaccination was extensively obtainable. Solely 5 of the 35 research addressed lengthy COVID.
Authors checked out each sequelae, together with signs that lasted lower than 4 weeks after symptom onset and lengthy COVID, outlined as signs lasting greater than 4 weeks after symptom onset.

Intercourse variations in outcomes have been reported throughout earlier coronavirus outbreaks, so the variations the present research suggests aren’t shocking, the group famous. Nevertheless, they stated that the majority research do not report granular information by intercourse, which supplies insights which may influence therapy.
They urged researchers to share disaggregated information, even when it wasn’t a part of the trial’s major focus, in order that different teams can discover variations between the sexes.
