Fig 3. Run charts showing the proportion of patients receiving individual elements of the CAP care bundle within 8 hours from admission.

Each dot represents 12–48 cases of CAP. The vertical, grey, dashed line denotes the beginning of the intervention period. The vertical, black, solid line marks the beginning of the follow-up period. The process centre (horizontal line representing the median) is frozen after the baseline period. Special cause variation can be identified by a red, dashed process centre (sustained shift) [36]. See S3.1–3.8 Figs in S1 File for run charts for the individual intervention sites along with information on the timing of our interventions.
