Log-rank test comparing survival of patients with SAPH vs IPAH. There is no difference in time-to-death between SAPH and IPAH. (Mean survival in months SAPH 62 ± 60 vs IPAH 46 ± 42, p = 0.28). Fig. 1b. Survival of SAPH Scadding stages 1-3 (non-fibrotic disease) is significantly greater than SAPH Scadding stage 4 (fibrotic disease) by log-rank test (Scadding stages 1-3 89 ± 79 months vs Scadding stage 4 42 ± 37 months p = 0.017). Survival of SAPH Scadding stages1-3 is also significantly greater than IPAH p = 0.02. There was no difference in survival between Scadding 4 and IPAH p = 0.43.
