Table 1. The odds ratios based on pairwise head-to-head comparisons.

	I. Fixed RR			II. Fixed RD
	B vs. A	C vs. A	C vs. B	B vs. A	C vs. A	C vs. B
Trial 1	1.59	2.25	1.42	3.00	4.85	1.62
Trial 2	1.62	2.35	1.45	2.60	4.10	1.58
Trial 3	1.66	2.47	1.49	2.36	3.65	1.55
Trial 4	1.70	2.61	1.54	2.20	3.35	1.53
Trial 5	1.75	2.79	1.60	2.08	3.14	1.51
Trial 6	1.80	3.00	1.67	2.00	3.00	1.50
Trial 7	1.86	3.27	1.76	1.94	2.90	1.49
Trial 8	1.93	3.63	1.88	1.90	2.83	1.49
Trial 9	2.02	4.12	2.04	1.87	2.79	1.50
Trial 10	2.12	4.85	2.28	1.84	2.78	1.51
Trial 11	2.25	6.00	2.67	1.83	2.79	1.52
Mean OR₁	1.66	2.90	1.97	2.45	3.54	1.54
Mean OR₂	1.85	3.40	1.80	2.15	3.29	1.53

OR = Odds Ratio; RR = Relative Risk; RD = Rate Difference; Mean OR₁ is the mean of ORs from the observed data assuming the greyed cells are not available as in many NMAs; Mean OR₂ is the mean of ORs from the full data assuming all the greyed cells are observed and available.
