OS: overall survival; PSG: portosystemic gradient; GV: gastric variceal; IM: immediate haemostasis; RB: rebleeding; C: complications; TS: technical success; H:haemostasis. ^◆Ninoi et al. compared TIPS with transcatheter sclerotherapy (including BRTO). We extracted relevant data about BRTO from the article. ^▲The mean duration of follow-up was 19.5 months for patients in the TIPS group (range, 1–52 mo.) and 18.2 months for patients in the BRTO group (range, 1–49 mo.). The follow-up period after the procedures was 41.2 ± 32.4 months in the TIPS group and 26.9 ± 16.5 months in the transcatheter sclerotherapy group (including BRTO). ^■Patients were followed up for 6 to 21 (mean, 14.4) months. _Not mentioned.
