ERRATUM TO: Cardiac Troponins in Low-Risk Pulmonary Embolism Patients: A Systematic Review and Meta-Analysis

© 2018 Society of Hospital Medicine


The authors would like to make the following corrections to their manuscript, Cardiac Troponins in Low-Risk Pulmonary Embolism Patients: A Systematic Review and Meta-Analysis (doi: 10.12788/jhm.2961), published online first April 25, 2018 (all corrections in bold):

  • The last sentence of the results section in the abstract should read: The pooled likelihood ratios (LRs) for all-cause mortality were positive LR 2.04 [95% CI, 1.53 to 2.72] and negative LR 0.72 [95% CI, 0.37 to 1.40].
  • In the "All studies pooled" of the last row of Table 2, Tn+ is corrected to 463. See revised table below.
  • On page E5, the first paragraph in the "Outcomes of Studies with Corresponding Troponin+ and Troponin-" section beginning with the fifth sentence should read as follows):

"In the pooled data, 463 (67%) patients tested negative for troponin and 228 (33%) tested positive. The overall mortality (from sensitivity analysis) including in-hospital, 30-day, and 90-day mortalities was 1.2%. The NPVs for all individual studies and the overall NPV are 1 or approximately 1. The overall PPVs and by study were low, ranging from 0 to 0.60. The PLRs and NLRs were not estimated for an outcome within an individual study if none of the patients experienced the outcome. When outcomes were only observed among troponin-negative patients, such as in the study of Moore (2009) who used 30-day all-cause mortality, the PLR had a value of zero. When outcomes were only observed among troponin-positive patients, as for 30-day all-cause mortality in the Hakemi9(2015), Lauque10 (2014), and Lankeit16 (2011) studies, the NLR had a value of zero. For zero cells, a continuity correction of 0.5 was applied. The pooled likelihood ratios (LRs) for all-cause mortality were positive LR 2.04 [95% CI, 1.53 to 2.72] and negative LR 0.72 [95% CI, 0.37 to 1.40]. The OR for all-cause mortality was 4.79 [95% CI 1.11 to 20.68, P = .0357].
