Corrigendum to “Non-Invasive Lung Impedance-Guided Preemptive Treatment in Chronic Heart Failure Patients: A Randomized Controlled Trial (Impedance-HF Trial)”: (Journal of Cardiac Failure (2016) 22(9) (713–722)(S1071916416300082)(10.1016/j.cardfail.2016.03.015))

The authors regret the following errors. (1) Table 2 • For “Primary efficacy endpoints, AHF hospitalizations up to 12 mo,” “Primary efficacy endpoints, AHF hospitalizations during entire follow-up,” “Secondary efficacy endpoints, All hospitalizations during entire follow-up (number, events per patient per year),” and “Secondary efficacy endpoints, Cardiac hospitalization during entire follow-up”: correct P value is <.001, not <.0001.• For “All-cause mortality during entire follow-up,” the correct HR, 95% CI, and P value are 0.55, 0.37–0.83, .004, not 0.52, 0.35–0.78, .002.• For “Cardiac mortality during entire follow-up,” the correct HR, 95% CI, and P value are 0.43, 0.26–0.70, <.001, not 0.41, 0.25–0.67, <.0001.• For “HF mortality during entire follow-up,” the correct HR, 95% CI, and P value are 0.32, 0.17–0.62, <.001, not 0.35, 0.15–0.58, =.0001.• Corrected text referring to Table 2 is:All-cause mortality during the follow-up period included 42 patients (33%) in the monitored group and 59 patients (46%) in the control group (rate 0.08 vs 0.14 per patient year follow-up, HR 0.55, 95% CI 0.37–0.83, P = .004, Table 2). CV death occurred in 26 (20%) and 47 patients (37%) (rate 0.05 vs 0.11, HR 0.43, 95% CI 0.26–0.70, P < .001) in the monitored and control group, respectively. During the entire study period, there were 13 deaths (10%) from HF in the monitored and 31 HF deaths (24%) in the control groups (rate 0.03 vs 0.08, HR 0.32, 95% CI 0.17–0.62, P < .001, Fig. 2D–F). There was no significant difference in the incidence of non-CV deaths (Table 2).(2) Other P values • Fig. 2A-C, Fig. 3, and Fig. 4, where the P value was listed as P < .0001, the correct P value is P < .001.(3) Fig. 2D-F • Fig. 2D (all-cause mortality): the embedded table for the number of patients at risk, the survival curves, and the P values were incorrect. The corrected Fig. 2D is shown.• Fig. 2E (cardiac mortality): P values were incorrectly listed as .000 for log rank and .001 for Breslow; the correct values are <.001 and <.001, respectively.• Fig. 2F (HF mortality): P values were incorrectly listed as .000 for log rank and .001 for Breslow; the correct values are <.001 and =.001, respectively.
