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)
QSTF=1, C=1F=0, C=0F=1, C=0F=0, C=1χ2 Test p valueκ
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.
