Medication Use Before and After Different Bariatric Surgery Procedures: Results from a Population-Based Cohort Study.
Observational study in Obesity surgery, 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
backgroundMetabolic and bariatric surgery improves most obesity-related comorbidities. Here, we evaluate the effect of different metabolic and bariatric surgery interventions on the use of medications to treat chronic conditions. MATERIALS AND
methodsThis was an observational population-based cohort study performed in Lombardy, Italy. Healthcare utilization databases were used to identify all residents who underwent a metabolic and bariatric surgery procedure between 2010 and 2020 with available follow-up data for at least three years after surgery. We included patients undergoing laparoscopic sleeve gastrectomy (LSG), gastric bypass (GB), laparoscopic adjustable gastric banding (LAGB), and biliopancreatic diversion (BPD).
resultsDuring the period 2010 to 2020, 19,450 patients (22.5% males, 13.5% with diabetes) underwent a metabolic and bariatric surgery procedure. LSG was the most commonly performed procedure (65%), followed by LAGB (19%), GB (15%), and BPD (1%). There was a significant reduction in the use of glucose-lowering and antihypertensive drugs after the procedure in all groups. Compared to LSG, the reduction in the use of glucose-lowering drugs was greater following GB (reduction at 3 years: 59 vs 65%, p-interaction < 0.001) and lower following LAGB (59 vs 25%, p-interaction < 0.001). There was a significant reduction in lipid-lowering drug use following LSG and GB (3-year reduction: 21 and 50%, p-interaction < 0.001), and in psychiatric drug use following LSG, GB, and LAGB (with no difference between groups). In all groups, proton pump inhibitor use increased during the first 6 months, followed by a decrease from 1 year afterward.
conclusionThe present study including a large number of patients undergoing metabolic and bariatric surgery procedures shows robust reductions in the use of glucose, blood pressure and lipid-lowering drugs at 3 years follow-up, suggesting benefits of surgery on both quality of life and healthcare costs.
