Agreement between experts for varying levels of ‘maximum acceptable difference’ This figure demonstrates the impact of varying limits for ‘maximum acceptable difference’ in WC ratings on level of agreement. Agreement is defined as the proportions of comparisons (in percentage, values in the bars) for whom the WC ratings between any two experts’ differ less than a prespecified limit, here, the ‘maximum acceptable agreement’. We used the expectations from a recent survey among stakeholders to specify the limits for ‘maximum acceptable difference’ (see Table 1 [6]).

Illustrative examples from the stakeholder survey [6]. a Treating and expert psychiatrists defined 25 percentage points* in work capacity ratings between two experts as the ‘maximum acceptable difference’. In RELY 1, 61.6% (109/177) of comparisons would fall within this limit versus 73.6% (170/231) of comparisons in RELY 2. b Lawyers, judges and insurers defined 20 percentage points* in work capacity ratings between two experts as the ‘maximum acceptable difference’. In RELY 1, 59.3% (105/177) of comparisons would fall within this limit versus 65.4% (151/231) of comparisons in RELY 2.
