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

Background: Malaysia has the highest obesity prevalence in Southeast Asia, driving the burden of type 2 diabetes mellitus (T2DM) and its healthcare costs. Long-term real-world cost-effectiveness data on bariatric surgery from Malaysia are absent. We evaluated the clinical outcomes, safety, and exploratory cost-effectiveness of bariatric surgery in Malaysian patients with obesity and T2DM. Methods: Retrospective cohort study of 180 patients undergoing laparoscopic sleeve gastrectomy or Roux-en-Y gastric bypass at HCTM, Universiti Kebangsaan Malaysia (2014-2016), with 5-year clinical follow-up. BMI and HbA1c were analysed using generalised estimating equations (GEE) with a Gaussian family, identity link and exchangeable working correlation. An exploratory cost-effectiveness analysis compared 20 surgical patients with 20 matched conventional-management patients (2012-2014) over a 10-year horizon from the healthcare-payer perspective. The incremental cost-effectiveness ratio (ICER) was expressed per 1% HbA1c reduction, with one-way deterministic and probabilistic sensitivity analyses. Results: Mean BMI decreased from 49.29 ± 8.97 to 25.33 ± 4.25 kg/m Conclusion: In this single-centre Malaysian cohort, bariatric surgery produced durable improvements in BMI and HbA1c with low complication rates and a favourable exploratory ICER. Findings should be interpreted in light of the retrospective design and small economic cohort, and confirmed in multicentre prospective studies.
