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.
