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

objectiveOne-third of Americans are obese and an increasing number opt for bariatric surgery. This study estimates the cost-effectiveness of common bariatric surgical procedures from a healthcare system perspective.

methodsWe evaluated the three most common bariatric surgical procedures in the US: laparoscopic gastric bypass (LRYGB), conventional (open) Roux-en-Y gastric bypass (ORYGB), and laparoscopic adjustable gastric banding (LAGB) compared to no surgery. The reference case was defined as a 53-year old female with body mass index (BMI) of 44 kg/m(2). We developed a two-part model using a deterministic approach for the first 5-year period post-surgery and separate empirical forecasts for the natural history of BMI, costs and outcomes in the remaining years. We used a combination of datasets including Medicare and MarketScan(®) together with estimates from the literature to populate the model.

resultsBariatric surgery produced additional life expectancy (80-81 years) compared to no surgery (78 years). The incremental cost-effectiveness ratios (ICERs) of the surgical procedures were US $6,600 per quality-adjusted life expectancy (QALY) gained for LRYGB, US $6,200 for LAGB, and US $17,300 for ORYGB (3 % discount rate for cost and QALYs). ICERs varied according to choice of BMI forecasting method and clinically plausible variation in parameter estimates. In most scenarios, the ICER did not exceed a threshold of US $50,000 per QALY gained.
