Summary: group cases of 120/96 or 120/120 in treatment/control group could achieve over 80% power to detect a 0.2000 difference between group proportions.

aConsidering the intervention effect, we assumed the relation of conforming cases between control/treatment group varied from 0.8–1.0/1.0.

bAssumed the detectable proportion of cases conformed to the defined “continuity of clinical service” is 0.5–0.7 in the treatment group and 0.3–0.5 in the control group.

Note: ① Type A for better cluster: larger and richer; type B for worse cluster: smaller and poorer. ② H for hypertension; D2 for diabetes 2. ③ Population, patient population and sample size are not averaged under “total average”. ④ All variables are compared with treatment group 1. ⑤ Distance is transferred into traffic time by public transportation. Time varies in accordance to the cluster terrain instead of linear map distance.
