^a Missing data: Data were missing for some variables, and the numerical descriptive statistics are based on the number of horses for which data were available. Data were missing for T in the cargo hold one hour before landing (missing = 17 horses, 14%), T in the jet stall one hour before landing (missing = 39 horses, 33%), T in the jet stall at take-off (missing = 43, 36%), H in the cargo hold one hour before landing (missing = 51 horses, 43%), H in the jet stall one hour before landing (missing = 62 horses, 53%), H in jet stall at take-off (missing = 65 horses, 55%). Median = band near the middle of the box, 25th percentile = bottom of the box, 75th percentile = top of the box, minimum = lower whisker, maximum = upper whisker
