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

backgroundRoux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) differ in their effects on body weight and risk for reoperation. However, it is unclear whether long-term health expenditures differ by procedure type in patients with diabetes.

objectiveTo compare health expenditures 3 years before and 5.5 years after bariatric surgery between patients with diabetes undergoing RYGB versus SG.

designRetrospective cohort study using target trial emulation principles.

settingIntegrated health system. PATIENTS: Patients with diabetes undergoing RYGB ( MEASUREMENTS: Total, inpatient, outpatient, and medication expenditures.

resultsCharacteristics of patients undergoing RYGB and SG were well balanced after weighting; 73% were female, average body mass index was 43.8 kg/m LIMITATION: Unobserved confounding.

conclusionOverall expenditures decreased substantially in the postsurgical period, primarily due to reductions in pharmacy expenditures, with no differences between RYGB and SG except in the first 6 months after surgery.
