Table 4.

A summary of blood pressure metrics (before program initiation, after program initiation, and the change in blood pressure). All values reported are means across the population subset, as well as across clusters identified through the clustering algorithm. Blood pressure values reflect the population mean of patient-level median blood pressures (mmHg). Reported P-values correspond to a Kolmogorov-Smirnov test that compares the distribution of blood pressure values before and after the care program was initiated.
