1 · What the graph read from it

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.

2 · The registry

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

objectivesEsophageal stricture is a significant complication of grade 2b and 3a esophageal injuries and causes much patient suffering. Preventing strictures would be beneficial to patients but there are currently no proven effective drugs. This study aimed to evaluate the effect of omeprazole for preventing esophageal stricture in adults with grade 2b and 3a corrosive esophageal injuries.

methodsThis study was an open single-center prospective randomized controlled trial that took place from April 2018 to January 2020. Patients were randomized to standard treatment or 80 mg/day intravenously × 3 days followed by 40 mg/day orally for 4 weeks. They were endoscoped at baseline and 4 weeks post discharge. Strictures were confirmed radiologically.

results20 patients were enrolled: 15 with grade 2b and five with grade 3a injuries. Standard care and omeprazole groups numbered 10 each. At 1 month, seven and two patients developed strictures in the standard and omeprazole groups, respectively, p = 0.024, for a risk reduction of 71.4%.

conclusionsOmeprazole reduced the risk of short-term developing esophageal strictures following grade 2b and 3a corrosive esophageal injuries. Larger studies are needed to reconfirm this finding. Thai Clinical Trials Registry (TCTR) number TCTR20190504001.
