Polymyxin B-induced gastric spasm:a case report.
Article in Frontiers in pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
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
Background: Polymyxin B is commonly used to treat carbapenem-resistant Acinetobacter baumannii (CRAB) infections, with increasing attention being paid to its effectiveness and adverse reactions. This article reports a rare case of gastric spasm as an adverse drug reaction caused by polymyxin B used for anti-infective treatment. Case presentation: A 14-year-old boy was diagnosed with a CRAB infection following surgery. He was treated with a combination of meropenem and polymyxin B for the infection, which led to severe abdominal colic symptoms in the patient. A comprehensive investigation into the potential causes of the severe abdominal colic was conducted clinically. Following the discontinuation of polymyxin B, the patient's severe abdominal colic symptoms gradually alleviated. Therefore, polymyxin B was identified as the causative factor for the gastric spasm in this patient. Results: Polymyxin B may induce gastric spasm in children by elevating histamine levels in the body. This increase in histamine enhances gastric acid secretion and triggers an inflammatory response, which collectively compromises the gastric mucosal barrier and promotes excessive contraction of the gastric smooth muscle.
