The table illustrates the probability of measurement 2 moving more than one quartile away from measurement 1 and vice versa for the heat/capsaicin, brief thermal sensitization (BTS) and burn injury models.

The distribution of the lowest (<25%) and highest (>75%) quartiles (rows [split into Measurement 1 and Measurement 2 observations]) divided in the 2 higher (≥50%) and the 2 lower (<50%) quartiles (columns), across the 3 different models. As an example: in the heat/capsaicin model the number of observations Measurement 1 with areas in the highest quartile (>75% [n = 47]) corresponded at Measurement 2 to 41 observations at or above the median (≥50%) and 6 observations below median value (<50%).
