Overall relation between the quality of the natural mentoring relationship on youth outcomes

Outcome	k	#ES	Mean r	95% CI	p	${\mathrm{\sigma }}_{\mathrm{level}2}^2$	${\mathrm{\sigma }}_{\mathrm{level}3}^2$	% Var. Level 1	% Var. Level 2	% Var. Level 3

Youth outcomes = academic and vocational, social‐emotional, physical health, psychosocial problems; k = number of studies; #ES = number of effect sizes; mean r = mean effect size (r); CI = confidence interval; ${\mathrm{\sigma }}_{\mathrm{level}2}^2$ = variance between effect sizes extracted from the same study; ${\mathrm{\sigma }}_{\mathrm{level}3}^2$ = variance between studies; % Var = percentage of variance distributed.
