−78.8% [−92.7%;−38.5%]

−33.6% [−48.9%; −13.7%]

−20.5% [−31.2%;−8.1%]

−17.6%

  1. For the SC method, we related the number of avoided cases to the number of observed cases in the synthetic control group. For the two-period DID, we used a log-transformed regression to calculate a semi-elasticity which is then transformed into relative effects. See “Methods” section for details. 95%-CI are reported in brackets.
