Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Quote: "The individuals were selected for the sample by the probability sampling method of simple random sampling. These individuals were listed for the simple random sampling method, and it was select 70 individuals from the table of random numbers including 35 in the experiment group and 35 in the control group."
Allocation concealment (selection bias)	Unclear risk	Insufficient information to understand whether intervention allocations could have been foreseen in advance of, during, enrolment.
Blinding of participants and personnel (performance bias) All outcomes	High risk	Participants were not blinded.
Blinding of outcome assessment (detection bias) All outcomes	High risk	Participants were not blinded whereas outcomes are self‐reported.
Incomplete outcome data (attrition bias) All outcomes	Low risk	Two of the participants in the experimental group were excluded from the study because they did not regularly participate in yoga practice. One of the participants in the control group was excluded from the study because he did not complete his final test. Unknown whether non‐completers differed from completers however loss to follow‐up is below our pre‐defined cut‐off point.
Selective reporting (reporting bias)	Unclear risk	No trial registration or no study protocol reported, nor did we find one online.
Other bias	Low risk	No indication of other sources of bias.
