Fig 6

The recurrence rate in the M1 group was slightly higher than that in the M2 group (P = 0.328; OR 1.161, 95% CI 0.861–1.564). The recurrence rate in the M0 group was higher than that in the M1 (P = 0.013; OR 2.877, 95% CI 1.246–6.643) and M2 groups (P < 0.001; OR 1.958, 95% CI 1.618–2.369). M0, induction BCG therapy only; M1, 1-year BCG maintenance therapy; M2, BCG maintenance therapy for more than 1 year.
