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

objectiveThis systematic review and meta-analysis aimed to identify common life-course body mass index (BMI) trajectories (childhood/adulthood to adulthood) and their impact on risk of cancer overall and cancer at different sites in adulthood.

methodsObservational studies were identified that assessed the association of BMI trajectories with cancer risks from databases published in English. The pooled effect sizes were estimated using a random-effects model.

findingsA total of 24 eligible studies were included in the meta-analysis. Transitioning from normal weight to obesity was significantly associated with an increased risk of colorectal cancer (effect size [ES] = 1.170, 95% CI: 1.096, 1.245), pancreatic cancer (ES = 1.337, 95% CI: 1.247, 1.426), kidney cancer (ES = 2.122, 95% CI: 1.619, 2.624), and liver cancer (ES = 1.777, 95% CI: 1.261, 2.293), compared to those in the stable normal weight trajectory. No significant difference in the risk of breast or prostate cancer was observed when comparing various BMI trajectories to a stable normal BMI trajectory.

conclusionThe findings suggest that lifetime BMI trajectories influence cancer risk, with a transition from normal BMI to higher levels associated with an increased risk of cancer. The impact varied by trajectory and cancer type. Further studies are needed to confirm these findings.
