Costs are converted from total charged amounts using cost to charge ratios, are reported in USD ($), and inflation adjusted to 2012 equivalents, based on Medical Consumer Price Index. No significant differences across quartile groups (variance-weighted least-squares regression, p=0.87 for hospital costs and p=0.78 for ICU costs).

Abbreviations: CI, confidence interval; IQR, interquartile range; ICU, intensive care unit; USD, US dollars.
