Evaluating the economic impact of bariatric surgery: A multi-year comparative analysis.
Article in American journal of surgery, 2026. 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
introductionBariatric surgery results in significant weight loss and improvement of obesity-related comorbidities, but data regarding its cost impact are mixed. We compared healthcare costs for bariatric surgery patients and non-operative controls through four years after surgery.
methodsPatients who underwent bariatric surgery in 2018-2019 were matched 1:5 with controls who met criteria for bariatric surgery but were medically managed. Post-operative costs were compared by year after surgery and healthcare setting.
resultsBariatric surgery patients (n = 37) had higher mean total costs years 1-4 after surgery compared to non-operative controls (n = 185) [$26,805(SD $47,039) vs. $14,547($30,170); p < 0.001]. The largest differences occurred in the outpatient setting [$16,935($19,807) vs. $8972($14,690); p < 0.0001] and during the first year after surgery [$12,616($36,422) vs. $3355($9367); p < 0.0001].
conclusionsBariatric surgery patients had higher post-operative costs through four years after surgery compared to non-operative controls, primarily due to higher costs within the first year after surgery and increased outpatient costs.
