Relationship between the axillary temperature and the surface temperature measured by an infrared thermoscanner. (A, C) Scatter plots examining the correlations between the surface temperature measured by an infrared thermoscanner and the axillary temperature. The straight line represents a fitted line by means of a least squares regression. The adjusted coefficients of determination, R2, were estimated to be 0.196 and 0.296 for the data shown in (A) and (C), respectively. (B, D) Comparison of the receiver operating characteristic curves showing the relationships between sensitivity (true positives) and 1-specificity (true negatives) in determining the diagnostic performances of the infrared thermoscanners for predicting three different thresholds of hyperthermia definitions (37.5°C, 38.0°C and 38.5°C) based on the axillary temperature. Panels A and B show the data for all the screened passengers (n = 1,049), while panels C and D show the data for the self-reporting passengers only (n = 285).
