Modelled change in the R ratio over time on day 7, day 14, and day 28 after the introduction of different composites of NPIs

	Day 7	Day 14	Day 28
Candidate 1: ban on public events and gatherings of more than ten people	0·94 (0·85–1·03)	0·87 (0·73–1·05)	0·71 (0·55–0·93)
Candidate 2: workplace closure plus ban on public events and gatherings of more than ten people	0·84 (0·76–0·93)	0·78 (0·64–0·94)	0·62 (0·47–0·82)
Candidate 3: Workplace closure plus ban on public events and gatherings of more than ten people plus internal movement limits	0·81 (0·71–0·92)	0·76 (0·60–0·95)	0·58 (0·41–0·81)
Candidate 4: School and workplace closure plus ban on public events and gatherings of more than ten people plus internal movement limits plus stay at home requirement	0·65 (0·54–0·78)	0·58 (0·42–0·78)	0·48 (0·32–0·71)

Data are R ratio (95% CI). The reference period is the day before introduction of an NPI. An R ratio of more than 1 indicates increased transmission, and an R ratio of less than 1 indicates decreased transmission. NPI=non-pharmaceutical intervention. R=time-varying reproduction number.
