Distribution of reviewer judgments by ATC classes in the purchase test, which measured correct purchases in this drug use period

		Classification			Total N		%
		Correct	Error	Non solvable		Correct	Error	Non solvable
ATC class	A	89	2	1	92	97	2	1
	B	44	0	0	44	100	0	0
	C	275	2	13	290	95	1	4
	G	37	1	0	38	97	3	0
	H	21	6	1	28	75	21	4
	J	28	12	0	40	70	30	0
	M	46	5	4	55	84	9	7
	N	325	8	4	337	96	2	1
	R	32	2	1	35	91	6	3
	OTHER	24	1	16	41	59	2	39
Total		921	39	40	1000	92	4	4

The category “OTHER” included classes D, L, P, S and V. These have been combined, due to the low numbers of purchases and poor data quality (high proportion of missing DDD values). The common names of ATC classes are found in Table 1.
