Table 3 Primary outcome assessment criteria

Diagnosis (Dx)
Single		Concurrent
If doctorDx = expert Dx	100 %	If doctorDx₁ + Dx₂ = expertDx₁ + Dx₂		100 %
If doctorDx ≠ expert Dx	0 %	If doctorDx₁ + Dx₂ ≠ expertDx₁ + Dx₂		0 %
		If doctorDx₁ = expertDx₁ and doctorDx₂ NA/≠ expertDx₂		50 %
Management (Mng)
Single		Multiple
If doctorMng = expertMng	100 %	Maximum number of correct Mng plans = 2	If doctorMng_1,2 = expertMng_{1, 2}	100 %
If doctorMng ≠ expertMng	0 %		If doctorMng_1,2 ≠ expertMng_1,2	0 %
			If doctorMng₁ = expertMng₁ and doctorMng₂ NA/≠ expertMng₂	50 %
		Maximum number of correct Mng plans = 3	If doctorMng_1,2,3 = expertMng_1,2,3	100 %
			If doctorMng_1,2,3 NA/≠ expertMng_1,2,3	0 %
			If doctorMng₁ = expertMng₁ and doctorMng_2,3 NA/≠ expertMng_2,3	33.3 %
			If doctorMng_1,2 = expertMng_1,2 and doctorMng₃ NA/≠ expertMng₃	66.6 %
		Maximum number of correct Mng plans = 4	If doctorMng_1,2,3,4 = expertMng_1,2,3,4	100 %
			If doctorMng_1,2,3,4 ≠ expertMng_1,2,3,4	0 %
			If doctorMng₁ = expertMng₁ and doctorMng_2,3,4 NA/≠ expertMng_2,3,4	25 %
			If doctorMng_1,2 = expertMng_1,2 and doctorMng_3,4 NA/≠ expertMng_3,4	50 %
			If doctorMng_1,2,3 = expertMng_1,2,3 and doctorMng₄ NA/≠ expertMng₄	75 %
Diagnosis		100 % = correct
		50 % = half correct
		0 % = incorrect
Management		100 % = fully correct
		>50 % = majority correct
		50 % = half correct
		<50 % = partially correct
		0 % = incorrect

These criteria determine the level of agreement between the non-specialist doctor and the overseeing expert
