CD47 and ovarian cancer: We found that CD47 mRNA expression level was positively correlated with worse OS among all ovarian cancer patients based on four different arrays (HR=1.16 (1.02-1.33), logrank P=0.025 for 211075_s_at; HR=1.18 (1.01-1.37), logrank P=0.033 for 213857_s_at; HR=1.33 (1.09-1.63), logrank P=0.0058 for 226016_at and HR = 1.23 (1-1.51), logrank P = 0.048 for 227259_at (Figures 4A–D).
