This table presents a comprehensive network meta-regression analysis to evaluate potential effect modifiers related to training dosage across eight performance outcomes. Variables including training frequency (Sessions/week), session duration (Minutes/session), and training intensity were analyzed to assess their impact on intervention efficacy and ensure the assumption of transitivity across the varied training volumes (1–16 weeks). Coefficients (Coef.) represent the change in Mean Difference (MD) per unit change in the modifier, with P-values in bold denoting statistical significance (P < 0.05). The lack of significant interaction for all training dosage variables across all eight outcomes (all P > 0.05) indicates that the comparative hierarchical rankings of the exercise modalities remain robust and stable regardless of variations in training exposure, further supporting the validity of the transitivity assumption within the studied range.
