•Temperature measured with IRT is not statistically equivalent to rectal temperature.•High-accuracy IRT is required to predict (calculate) body temperature.•Linear-regression prediction is adequate for body temperature prediction.•IRT may be used as a screening tool to detect suspiciously elevated t...
