We documented a univariate dose-response relationship between severity of OSA and hs-cTnT levels. Dr Argulian further suggests investigating the association between the top quartile of hs-cTnT and the severity of OSA. Based on this suggestion, we substituted our dependent variable (detectable hs-cTnT >3 ng/L) with the top quartile (>5.61 ng/L). By logistic regression analysis, an apnea-hypopnea index of 5 to 29.9 was associated with an OR of 1.86 (95% CI, 1.17-2.98) for hs-cTnT in the top quartile, and an apnea-hypopnea index of ≥30 was associated with an OR of 4.47 (95% CI, 2.50-7.90). However, in a multivariate model, OSA did not emerge as an independent predictor of hs-cTnT in the upper quartile in this population-based cohort, confirming the conclusion drawn in our original report.
