LUM and endometriosis: Expression of LUM (identified in 3 spots) was higher in the secretory phase endometriosis group compared to both control groups (e.g. spot 708; ES/CS = 1.86, P = 0.005; ES/PS = 2.25, P = 0.004) and in ectopic compared to eutopic tissue (EcS/ES = 2.09, P = 0.008), but not in proliferative phase samples (Additional file 1: Table S2).
