Stepped-wedge roll out of ASi by ward and month.
C = control months and X = intervention months.
Fig 2.
Temporal trends of HA-CDI and CA-CDI by (a) total, and (b) ward. The smooth trend line in (a) was calculated from the time series using a locally weighted smoothing function (lowess). The vertical reference lines in (b) represent the start date for ASi for that ward.

Fig 3.
Temporal trends of ASi consults and number accepted by (a) total, and (b) ward. The vertical reference lines in (a) represent the different start dates for ASi.
