Estrogen receptor beta (ERβ) expression in ductal pancreatic adenocarcinoma. Percentages of ERβ expressing tumors are shown by stratification into tumor dependent death after less than 12 and more than 12 but less than 24 months, and overall survival more than 24 months. Significantly fewer tumors of long-term overall survivors expressed ERβ, compared to other strata (p = 0.043, < 24 months versus 12–24 months; p = 0.0026, > 24 months versus < 12 months; p = 0.000099, > 24 months versus < 24 months)
