Japanese Patients With Obesity-Related Bronchial Asthma May Benefit From Laparoscopic Sleeve Gastrectomy.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
backgroundWeight loss can effectively improve asthma control for some patients with obesity-related bronchial asthma, but it is difficult in certain patients. Bariatric surgery may enhance asthma control in such patients.
objectivesWe evaluate the effects of laparoscopic sleeve gastrectomy (LSG), as an example of bariatric surgery, on asthma control in patients with obesity-related bronchial asthma.
methodsWe analyzed 521 of our patients who underwent bariatric surgery between June 2016 and February 2024. They each had a self-reported history of bronchial asthma and were receiving treatment for it at the time of surgery. We assessed Asthma Control Test (ACT) scores, short-acting beta agonist (SABA) use based on the ACT, and respiratory function tests before and after surgery. Statistical analysis was performed using Wilcoxon's signed rank test, with significance defined as P < 0.05.
resultsFifteen patients were included (86.7% female, median age: 46 years, median body mass index (BMI): 41.0 kg/m², median ACT score: 22). Fourteen of them underwent only LSG; the other also had duodenal bypass. The median percentage total weight loss at six months post surgery was 21.8%. ACT scores improved from 20.8 ± 3.5 to 24.4 ± 1.2 points (P = 0.0039), forced expiratory volume in 1 second (FEV1) increased from 2.45 ± 0.47 L to 2.74 ± 0.51 L (P = 0.0001), and SABA use decreased by 86.7%, indicating that the patients had better bronchial asthma control than before surgery.
conclusionLSG appears to improve asthma control in certain patients with obesity-related bronchial asthma.
