All means are adjusted by enrollment site (Upstate New York/New York City). Semi-parametrically weighted means are also adjusted by the cumulative probability of not being censored. 95% CIs, estimated from robust standard errors, which were adjusted for clustering by primary care physician practices. Only p values <0.05 for the comparison between the usual care and telemedicine groups are shown.
