The following sentence on page 499 was incorrect in the published paper:
In a total of 9266 matched patients (4633 participants in both cohorts), adherence was significantly higher in the RP cohort compared with patients in the non-RP cohort (medication possession ratio, RP 80% versus non-RP 73%; proportion of days covered, RP 76% versus non-RP 63%; both P < 0.001).
The correct sentence should read:
In a total of 9266 matched patients (4633 participants in both cohorts), adherence was significantly higher in the RP cohort compared with patients in the non-RP cohort (medication possession ratio, RP 80% versus non-RP 73%; proportion of days covered, RP 65% versus non-RP 63%; both P < 0.001).
Also on page 504 the following sentence was incorrect in the published paper:
With similar baseline adherence (medication possession ratio 82%), the post-index adherence was significantly higher in the RP cohort (patients who switched from valsartan-hydrochlorothiazide combination therapy without RP to valsartan-hydrochlorothiazide combination therapy with RP) compared with the non-RP cohort (valsartan-hydrochlorothiazide combination patients who did not switch to RP, medication possession ratio 80% for RP cohort versus 73% for the non-RP cohort; proportion of days covered 76% for RP group versus 63% for non-RP group; both P < 0.001, Table 2).
The correct sentence should read:
With similar baseline adherence (medication possession ratio 82%), the post-index adherence was significantly higher in the RP cohort (patients who switched from valsartan-hydrochlorothiazide combination therapy without RP to valsartan-hydrochlorothiazide combination therapy with RP) compared with the non-RP cohort (valsartan-hydrochlorothiazide combination patients who did not switch to RP, medication possession ratio 80% for RP cohort versus 73% for the non-RP cohort; proportion of days covered 65% for RP group versus 63% for non-RP group; both P < 0.001, Table 2).
