Table 6 Differences in minimal-to-adequate guideline adherence between intervention and control group. Number of medical records in which guideline-based care was minimal-to-adequate (score 1 and 2) consistent with the guideline, their percentage scores (performance rate) and differences (p-value, risk differences and 95% confidence interval) between intervention group and control group (chi-square test)
