Fig 2 Duration of arterial perfusion temperatures during cardiopulmonary bypass (CPB) rewarming. Box and whisker plot of cumulative time during CPB that arterial outlet temperature was greater than 36°C, greater than 36.5°C, and greater than 37°C (N = 5,042, 3,900, 1,014, respectively). Box indicates median and interquartile range, upper whisker indicates all data points within 1.5 of the upper quartile stopping at largest value; values greater than this are outliers.

Fig 3 Lowess smoothing plot of mean rewarming temperature greater than 36°C and incidence of acute kidney injury (AKI). Plot confirms that there is an increase in probability of AKI only for temperatures greater than 37°C.
