Leucopenia * B symptoms present Performance status level 2–4 Bone marrow aspirate positive Age 75 years or older PMitCEBO given GCSF given Bone marrow trephine positive Stage 3 or 4 LDH elevated Anaemia ** B symptoms present LDH elevated GCSF given Bone marrow aspirate positive Performance status level 2–4 Bone marrow trephine positive Thrombocytopenia *** B symptoms present Performance status level 2–4 LDH elevated Bone marrow trephine positive PMitCEBO given Stage 3 or 4 Bone marrow aspirate positive Age 75 years or older GCSF given * The multivariate model is for 560 patients with complete data on all variables included in it. ** The multivariate model is for 597 patients with complete data on all variables included in it. *** The multivariate model is for 522 patients with complete data on all variables included in it. # Odds ratio @ Confidence interval Univariate OR# (95% CI@) 2.0 (1.5–2.8) 3.0 (2.1–4.3) 2.3 (1.3–4.1) 1.8 (1.3–2.6) 2.4 (1.7–3.3) 0.6 (0.4–0.8) 2.1 (1.3–3.4) 1.8 (1.3–2.5) 1.4 (1.02–2.0) 2.3 (1.2–4.3) 2.9 (1.3–6.7) 2.6 (1.3–4.9) 2.5 (1.1–5.8) 2.1 (1.2–3.9) 1.9 (0.9–4.1) 2.7 (1.5–4.8) 4.8 (2.8–8.2) 6.7 (2.6–17.0) 2.8 (1.5–5.2) 0.6 (0.4–1.0) 3.2 (1.6–6.2) 2.7 (1.4–5.6) 2.0 (1.2–3.4) 1.7 (1.0–2.8) p < 0.001 < 0.001 0.006 0.001 < 0.001 0.001 0.002 < 0.001 0.038 0.013 0.011 0.004 0.030 0.013 0.088 0.001 < 0.001 < 0.001 0.001 0.058 0.001 0.005 0.011 0.058 Multivariate OR# (95% CI@) 1.7 (1.2–2.4) 2.2 (1.5–3.3) 2.2 (1.2–4.0) 2.1 (1.4–3.1) 2.1 (1.5–3.0) 0.5 (0.4–0.8) - - - - - - - - - - - 2.3 (1.1–4.7) 2.6 (1.1–6.1) 2.3 (1.1–4.5) 4.8 (2.5–9.2) 4.0 (1.5–10.4) 2.9 (1.4–5.8) 0.5 (0.3–0.9) p 0.005 < 0.001 0.015 < 0.001 < 0.001 0.001 0.025 < 0.001 0.020 < 0.001 0.005 0.003 0.032 Page 8 of 10 (page number not for citation purposes)
