*In the case of quantitative variables linear regression was used; β standardized linear regression coefficient; OR odds ratio; CI confidence interval; FD Family dependent; LI Locally integrated; LS-C Local self-contained; WCF Wider community focused; PR Private restricted; U Unclassified

Significant differences are marked in bold. In all analyses, a two-tailed P value of less than 0.05 was regarded as significant
