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

purposeObesity increases the risk of breast cancer (BC), and bariatric surgery may lower overall cancer risk. However, the impact of sleeve gastrectomy (SG) timing on cancer outcomes remains unclear. PATIENTS AND

methodsUsing the TriNetX global health research network, we identified 4,439,072 women diagnosed with severe obesity (BMI >35 kg/m

resultsSG was associated with lower 5-year all-cause mortality across all timing groups compared to the control group. Early SG was significantly associated with a reduced 5-year incidence of BC (risk ratio [RR]: 0.799; 95% CI: 0.647 to 0.987; P = .037), gynecologic cancer (RR: 0.490; 95% CI: 0.378 to 0.635; P < .001), and metastasis (RR: 0.306; 95% CI: 0.230 to 0.408; P < .001). By contrast, delayed SG was associated with an increased risk of BC (RR: 1.404; 95% CI: 1.107 to 1.781; P = .005). Age-stratified analyses indicated that the association between SG timing and outcomes appeared more pronounced in patients aged ≥45 years.

conclusionsOur findings highlight the importance of timely bariatric surgery in optimizing both metabolic and oncologic outcomes, particularly in older women with obesity.
