Change in power from group adjudication compared to independent adjudication. This figure shows the change in power from using group adjudication compared with independent adjudication when outcomes are adjudicated by central assessors. The intraclass correlation coefficient (ICC) represents the degree of correlation between different assessors, with a value of zero indicating no more agreement between assessors than would be expected by chance, and a value of one indicating perfect agreement between assessors. The false-positive and false-negative rates for independent adjudication are 20%, and the ICC was 0.50
