*4.4. Study Selection and Data Extraction*

Two reviewers (S.P. and A.B.) independently identified studies that met the inclusion criteria and performed data extraction. Disagreements between the reviewers were resolved by discussion. From each selected study, the following data were extracted: author, year of publication, mean age of

the participants, study design (sample size, intervention type, follow-up duration, and frequency of intervention), and outcome measurement tools.
