Error Bars from Scientific Research

Data are represented as hazard ratio (HR) 95% confidence interval (CI). PFS was summarized using the Kaplan-Meier method with associated two-sided 95% CIs calculated using the Brookmeyer and Crowley method. HRs were obtained from the unstratified Cox proportional hazard model. Nine patients were included in multiple groups, including one patient with mutations in KIT exon 9 and KIT exon 11 and eight patients with mutations in KIT exon 11 and PDGFRA ; the exon 11 + 13/14-only group excludes patients with mutations in KIT exons 9, 17 and 18; the exon 11 + 17/18-only group excludes patients with mutations in KIT exons 9, 13 and 14. Data cutoff: 1 September 2021.
