ICC 0.069
  1. ICC Intra-cluster correlation coefficient. The between group variance and ICC was computed to see VIA test positivity (dependent variable) variability among type of health center cluster s (independent variable) as per multilevel mixed effects models for logistic regression. ICC = 0.245/(0.245 + π2/3) = 0.245/3.535 = 0.069
