Although the overall effect was not significant, subgroup analysis based on PA intensity revealed that the result in the low-intensity group approached significance (MD = −4.97, 95% CI: −9.89, −0.05, p = 0.05), with a larger effect size than that in the moderate-to-vigorous-intensity group (MD = −0.31, 95% CI: −1.28, 0.65, p = 0.53).
Although the overall pooled analysis showed no statistically significant effect of the intervention, a clear trend was observed in the PA intensity subgroup analysis based on our pre-specified subgroup analyses.
The results indicated that the overall combined effect size of the intervention did not reach statistical significance when the MABC or MABC-2 scale was used as the assessment tool.
While low-intensity activities appeared to show a favorable trend, this finding should be interpreted with caution, given the limited number of studies and differences in study design.
