Fig. 5

Relationship of total staff and summary measure of outputs of the health centers. Note (b) and (c) examine the staff and output relationship at lower staffing levels in more detail. For the ease of visualization, the range of total staff and output was truncated from 0 to 40. The red line indicates the locally weighted smoothing (lowess) curve. The density curves in (b) and (c) represent the observations between the sections of 0–10, 11–20, 21–30, and 31–40
