Bland—Altman plots during rest illustrating the mean bias (dashed line) and 95% limits of agreement (mean difference ± 1.96 · modified standard deviation: dotted lines) for thermistors vs iButtons (a), thermistors vs infrared thermometer (b) thermistors vs infrared camera (c).

<p>Each participant is represented by a unique colour or shape (<i>n</i> = 30). Grey band indicates the practically meaningful, a priori acceptable mean bias (± 0.5°C).
