Manfredini F, Mallamaci F, D’Arrigo G, Baggetta R, Bolignano D, Torino C, Lamberti N, Bertoli S, Ciurlino D, Rocca-Rey L, Barillà A, Battaglia Y, Rapanà RM, Zuccalà A, Bonanno G, Fatuzzo P, Rapisarda F, Rastelli S, Fabrizi F, Messa P, De Paola L, Lombardi L, Cupisti A, Fuiano G, Lucisano G, Summaria C, Felisatti M, Pozzato E, Malagoni AM, Castellino P, Aucella F, Abd ElHafeez S, Provenzano PF, Tripepi G, Catizone L, Zoccali C: Exercise in patients on dialysis: A multicenter, randomized clinical trial. J Am Soc Nephrol 28: 1259–1268, 2017. In the second sentence following the heading, “Secondary Outcomes: Death, Cardiovascular Events, and Hospitalizations” on p. 1262, the authors erroneously stated, “…in an analysis restricted to patients who completed the trial, the hospitalization-free survival was lower (P=0.04) in patients in the active group than in the control group.” Because there were 35 hospitalizations per 100 person-years in patients of the active arm and 57 hospitalizations per 100 person-years in those of the control arm (as correctly reported in the same paragraph of the paper), the correct sentence should be “…in an analysis restricted to patients who completed the trial, the hospitalization-free survival was higher (P=0.04) in patients in the active group than in the control group.” The authors apologize for the error.
