13 November 2022	New citation required and conclusions have changed	The change in conclusions is primarily that there is now a higher level of confidence in evidence on comparisons between yoga and other exercise for back related function. The certainty of evidence for little or no difference in back‐specific functional status between yoga and non‐yoga exercise has increased. There is new information on pain for the comparison between yoga and non‐yoga exercise. There is new evidence on work‐related disability on yoga compared to qigong. In 2017 the certainty of the evidence was very low at 3‐4 months and 6 months, while in 2022 the certainty of evidence for little or no difference is moderate at 3‐4 months and low at 6 months.
