Kaplan-Meier survival functions according to BCL2 protein expression levels. Overall survival based on 242 case subjects with total time at risk 1846.10 years. 1: low expression (immunohistochemistry score zero or 1), 2: moderate expression (immunohistochemistry score 2), 3: high expression (immunohistochemistry score 3). Numbers at risk at the end of the 10-year analysis period were 18 (low expression), 39 (moderate expression) and 97 (high expression). Hazard ratio (99.5% CI) 0.69 (0.51, 0.93), p = 0.015.
