What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundRefractory esophageal stricture is difficult to deal with. Some refractory stricture shows little response to now-existing endoscopic techniques. We assessed the efficacy of modified endoscopic radial incision and cutting method (M-RIC) for the treatment of refractory esophageal stricture.
methodsThis was a retrospective study. Patients with refractory esophageal stricture who underwent M-RIC or dilation from June 2016 to June 2020 were included. Outcomes measured included technical and clinical success, restenosis rate, time to restenosis and complications. Risk factors for restenosis after M-RIC were assessed.
results67 patients were enrolled (M-RIC group, n = 29; dilation group, n = 38). After propensity score matching, each group include 28 patients. There were no significant differences in technical success (96.4% vs 100%, p = 1.00) or clinical success (89.3% vs 100%, p = 0.23) between groups. Patients in M-RIC group had lower rates of restenosis (75% vs. 100%, p = 0.02) and longer time to restenosis (110 days vs 31.5 days, p = 0.00) compared with dilation group. 4 patients did not require any additional treatment after M-RIC and maintained food intake until the end of follow-up. Complications of M-RIC include perforation, fever and retrosternal pain, and no difference was found in total complication rate when compared with dilation group (25% vs 7.1%, p = 0.07). Although 3 out of 28 patients (10.7%) in M-RIC group had perforation, the perforation rate was not significantly different between groups (p = 0.11). Multivariate analyze suggested stricture length ≥ 5 cm (HR 7.25, p = 0.00) was a risk factor to restenosis while oral prednisone (HR 0.29, p = 0.02) was associated with preventing restenosis after M-RIC.
conclusionM-RIC is a feasible and effective technique for refractory esophageal stricture with lower rate and longer time to restenosis. Stricture length ≥ 5 cm is a risk factor to restenosis while oral prednisone is helpful in remitting restenosis after M-RIC.
