From: Unsatisfactory reproducibility of interstitial inflammation scoring in allograft kidney biopsy

Pairwise inter-rater reliabilities of interstitial inflammation scorings grouped in rater pair order. The upper dashed line indicates a kappa value of 0.4, which is regarded as the lower limit of moderate agreement. The lower dashed line indicates the total average of all kappa values. Red, blue, and purple boxes and whiskers indicate the i score, ti score, and i-IFTA, respectively. Error bars: 95% confidence interval.
