IQR: Interquartile range; A Summary index of load carrying generated using polychoric principal component analysis of load-carrying duration, frequency, and weight. Dichotomized using the median index score to indicate “low” or “high” load-carrying exposure. B Self-reported load-carrying duration 0.1 min per load was representative of durations <1 min.
