BECN1 and disseminated peritoneal leiomyomatosis: Correlation analyses for the western blot data obtained before and after LPD showed that the BECN1 levels of muscle biopsies and leukocytes faintly correlated at T0 (R = 0.467, P = 0.091) and significantly correlated at T12 (R = 0.630, P = 0.033), whereas no correlation was found between muscles and leukocytes for the LC3B-II protein levels (baseline visit: R = 0.085, P = 0.527; T12 visit: R = 0.139, P = 0.410).
