A two-level random intercept logistic regression model was fitted, defined as $\\logit(p{ij}) = \\beta0 + \\beta X{ij} + uj$, where $p{ij}$ is the probability of successful outcome for patient $i$ in clinic $j$, $X{ij}$ are patient-level covariates, and $uj \\sim N(0, \\sigma^2u)$ represents the clinic-specific random effect.
