Self-expandable metallic stents may be more efficient than balloon dilatation alone for esophageal stricture after circumferential endoscopic submucosal dissection: a retrospective cohort study in China.

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
introductionSelf-expandable metallic stents (SEMSs) can be used to treat esophageal stricture after circumferential endoscopic submucosal dissection (ESD), but its efficacy and placement timing remain to be determined. In this study, the treatment time and number of dilatations were compared between the SEMS placement group and the balloon dilatation (BD) group to clarify the efficacy and placement time of SEMSs in the treatment of esophageal stricture after circumferential esophageal ESD.
methodsThis was a retrospective cohort study. Patients with esophageal stricture after circumferential ESD between January 2015 and January 2020 were included. Data on the patients' demographic characteristics, esophageal lesion-related factors, esophageal stricture occurrence, and measures taken to treat the stricture were collected. The primary outcome was the treatment time, and the secondary outcome was the number of dilatations.
resultsThe total number of dilatations was 30 in the SEMS group and 106 in the BD group. The average number of dilatations in the SEMS group (1.76 ± 1.64) was significantly lower than that in the BD group (4.42 ± 5.32) (P = 0.016). Among the patients who underwent SEMS placement first had a shorter treatment time (average 119 days) than those who underwent BD first (average 245 days) (P = 0.041), and the average number of dilatations inpatients who underwent SEMS placement first (0.71 ± 1.07) was significantly lower than that in the patients who underwent BD first (2.5 ± 1.54).
conclusionSEMSs were more efficient in the treatment of esophageal stricture in a cohort of patients after circumferential esophageal ESD.
