Displayed are average, minimum or maximum values of P and NP, and the difference between them (Δ). Initial and follow-up data (see Methods) are presented separately. Negative numbers indicate that the value is lower in P; positive numbers, higher. Statistical significance of differences: ***p <0.001; **p <0.01; *p <0.05; NS, not significant. % of values under test name indicate proportion of patients having had the test.
