Reproducibility of outcomes between field and clinic, showing number of concordant and discordant pairs of measurements, together with χ2 test of association and κ statistic
| Concordant (F=C) | Discordant (F≠m`C) | |||||

| QST | F=1, C=1 | F=0, C=0 | F=1, C=0 | F=0, C=1 | χ2 Test p value | κ |
| An abnormal test result in the field (F) or clinic (C) is denoted by a 1, a normal result by 0. QST, quantitative sensory testing. | ||||||
