The GRADE tool for the pooled results in the patients after concurrent training.

Outcomes		Illustrative comparative risks* (95% CI) Corresponding risk	Number of participants (studies)	Certainty of the evidence
Pain	VAS score	The VAS score of scapular stability training group was significantly better than that of control group [WMD = −0.81, 95% CI (−1.11, −0.51), p < 0.001]	327 (7 studies)	Low★+
Function	SPADI score	The SPADI score of scapular stability training group was significantly better than that of control group [WMD = −10.10, 95% CI (−18.87, −1.33), p = 0.02]	150 (3 studies)	Very low★‡+
ROM	Flexion	No significant difference in the active flexion range of the shoulder joint between groups [WMD = 1.20, 95% CI (−0.81, 3.21), p = 0.24]	65 (3 studies)	Low★‡
	Abduction	There was no significant difference in the flexion amplitude of shoulder joint movement between the two groups [WMD = 1.20, 95% CI (−0.81, 3.21), p = 0.24]	100 (4 studies)	Very low★‡+
	External rotation	After the treatment, there was no significant difference in ROM mobility between groups [WMD = 2.89, 95% CI (−3.30, 9.08), p = 0.36]	50 (4 studies)	Very low★‡+
	Internal rotation	The analysis of random-effect models revealed no significant differences between groups [WMD = −0.87, 95% CI (−6.04, 4.31), p = 0.74]	50 (2 studies)	Very low★‡+
