MH, metatarsal head; SD, standard deviation.
*
Values are mean (standard deviation) in °C, or as indicated.
†
The left‐to‐right temperature difference was first calculated at an individual level (i.e. difference between warmer and colder foot), after which the mean difference was calculated over these individual outcomes; the foot with a higher temperature was labelled ‘warmer foot’, and differences were calculated as ‘warmer minus colder’, hence always greater than zero. This calculation was performed per location and mean left‐to‐right difference.
