Because the structural instead of functional parts of societal relationships may dictate wellness in another way ,, this new large degree of heterogeneity seen in this new omnibus performance could possibly get have been due simply to help you differences when considering the constituents of personal dating evaluated contained in this and you can all over knowledge. And this the remaining analyses by themselves check impact models extracted from structural, functional, and you will mutual (structural and you will practical) tips off personal dating.
Structural aspects of societal dating.
Sixty-three studies had data exclusive to structural measures of social relationships (see Figure 3). Across these studies, the random effects weighted average effect size was OR = 1.57 (95% CI = 1.46 to 1.70), which value fell within the CI of the omnibus results reported previously. The heterogeneity across studies was still quite large (I 2 = 84% [95% CI = 80% to 87%]; Q(62) = 390, p<0.001; ? 2 = 0.07), so we undertook metaregression with prespecified participant and study characteristics.
Metaregression is an analogue to multiple regression analysis for effect sizes. Its primary purpose is to ascertain which continuous and categorical (dummy coded) variables predict variation in effect size estimates. Using random effects weighted metaregression, we examined the simultaneous association (with all variables entered into the model) between effect sizes and prespecified participant and study characteristics (Table 3). To examine the most precise effect size estimates available and to increase the statistical power associated with this analysis, we shifted the unit of analysis and extracted effect sizes within studies that were specific to measures of structural aspects of social relationships.
