Descriptive statistics were performed for all study variables. Continuous variables were expressed as mean ± standard deviation (SD) or median (interquartile [IQR]) for skewed variables. Categorical variables were expressed as percentages. Normality of data was tested using the Kolmogorov-Smirnov test. Comparison of continuous variables was performed using Student’s t-test or the Mann-Whitney U-test, and of binominal variables using the
χ2 or Fisher exact test, respectively. Comparison between three groups was performed using one-way ANOVA for continuous data. Univariable and multivariable Cox regression models were used to evaluate potential predictors of in-hospital mortality and MACE.
Kaplan-Meier survival curves were used to compare event-free and survival rates for COVID-19 patients by the log-rank test. Receiver operating characteristics (ROC) curves were constructed to determine the ability of baseline cTn T to predict mortality and MACE and to identify its sensitivity and specificity.
Data were analyzed using IBM
SPSS Statistic for Windows, Version 26.0 (Armonk, NY: IBM Corp.). A p value < 0.05 was considered significant.
