Agreement of secondary hyperalgesia areas in the heat/capsaicin (<b>left part of table</b>), brief thermal sensitization (BTS [<b>middle part of table</b>]) and the burn injury (<b>right part of model</b>) model, at <b>Measurement</b><b>1</b> (rows) and <b>Measurement 2</b> (columns).

Data indicate the distribution of observations split into quartiles (<25%, 25–50%, 51–75%, >75%) giving a 4×4 contingency table (total number of observations for each quartile are indicated in lower row [Measurement 2] and right-hand column [Measurement 1]). The numbers in the lower right-hand corner, in each panel, are the total number of observations. The numbers in bold indicate completely agreement between observations: Measurement 1 and Measurement 2. Perfect agreement for the heat/capsaicin (A), brief thermal stimulation (B) and the burn injury (C) models were seen in 51%, 54% and 49% of the observations, respectively. The weighted Cohen’s kappa statistics were 0.66 (95% CI: 0.57–0.74) for the heat/capsaicin model, 0.74 (0.65–0.82) for the brief thermal stimulation and 0.74 (0.65–0.82) for the burn injury model.
