Flow chart of patient enrollment and exclusion. Among the 1268 enrolled patients, 378 patients were excluded for the analysis at M6 because of lack of PTH value; moreover, 80 patients in this group were no longer taking cinacalcet-HCl at M6. At M12, another additional group of 95 was excluded for the same reason, and among them 130 patients were not taking cinacalcet-HCl. Overall, we identified 652 patients who could be analysed at the end of the 36 month period of the study. EOS, end of study.
