Statistical analysis plans
Generalized estimating equation (GEE) with work matrix of first-order autoregressive factor will be used to the effects of the implementation of the intervention after the baseline assessment. Missing data will be treated as missing at a random mechanism via restricted maximum likelihood. The adopted significance level is 0.0125 (due to the four correlated outcomes, reducing the false discovery rates). For interobserver quality check, we will calculate the interobserver agreement using intraclass correlation (ICC) [
