Study characteristics
Methods	Study design: randomised controlled trial Study grouping: Parallel group
Participants	Baseline characteristics Mindfulness‐based Yoga Age (mean ± SD): 42 ± NR Sex (N (% female)): 38 (95%) Sample size: 41 Years of experience (mean ± SD): NR Control (no intervention) Age (mean ± SD): 42 ± nr Sex (N (% female)): 35 (95%) Sample size: 37 Years of experience (mean ± SD): NR Overall Age (mean ± SD) : 42 ± 12.1 Sex (N (% female)): NR Sample size: 78 Years of experience (mean ± SD): NR Included criteria: employees who provided direct patient care (including but not limited to nurses, nursing assistants, therapists, physicians, and social workers), older than 18 years. Excluded criteria: the presence of joint or muscle problems that limited mobility (e.g. advanced arthritis, herniated disk, or past injuries that prevent painless or safe movement), having routinely practised yoga or any other MB intervention in the past 6 months, or currently on medication that might interact with the results of salivary cortisol measures, including prednisone, cortisone, or steroid‐based medicine. Pretreatment: reported socio‐demographic baseline characteristics of participants randomised to the intervention group were similar to socio‐demographic baseline characteristics of participants randomised to the control group. Compliance rate: there was 98.7% attendance across all sessions for those in the MB yoga intervention group. Response rate: NR Type of healthcare worker: Nurses & other healthcare professionals
Interventions	Intervention characteristics Mindfulness‐based Yoga Type of the intervention: Intervention type 2 ‐ to focus one’s attention away from the experience of stress Description of the intervention: Based on a combination of Hatha and Raja Yoga practices. The MB yoga intervention was a beginner level program, starting with seated centering, brief teaching about yoga focused attention on the breath, and yogic breath practice (complete yogic breath and alternate nostril breathing). The number of sessions: 6 weeks Duration of each session on average: NR Duration of the entire intervention: 6 weeks Duration of the entire intervention short vs long: Short Intervention deliverer: NR Intervention form: NR Control (no intervention) Type of the intervention: NA Description of the intervention: NA The number of sessions: NA Duration of each session on average: NA Duration of the entire intervention: NA Duration of the entire intervention short vs long: NA Intervention deliverer: NA Intervention form: NA

Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Quote: "Once identified as eligible, participants signed consent, completed subjective assessments, and were randomly assigned to the intervention or control group using a computerized randomization tool."
Allocation concealment (selection bias)	Unclear risk	Difficult to judge whether participants and/or investigators could possibly foresee assignment. However, it is assumed that randomization was performed in one go and that participants and/or investigators could not foresee the assignment.
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	Quote: "Two members of the control group were not able to participate in collection of post‐intervention data, due to personal time constraints, yielding an attrition rate of 2.5%."
Selective reporting (reporting bias)	Unclear risk	No trial registration or no study protocol reported, nor did we fine one online
Other bias	Unclear risk	Response rate not reported.
