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

Diabetes increases fracture risk, but whether this risk varies by age at diagnosis is unclear. In a large cohort of Australian women, younger age at diabetes diagnosis was linked to substantially higher fracture risk. Age at diagnosis may enhance fracture risk assessment and guide targeted prevention. PURPOSE: The purpose is to examine whether age at diabetes diagnosis modifies the association between diabetes and fracture risk in women.

methodsWe used data from 12,170 participants in the 1946-1951 cohort of the Australian Longitudinal Study on Women's Health, linked with administrative health records. Women were followed from age 27 to 76 years. Diabetes status, age at diagnosis, and fracture events were identified from survey and administrative data. Poisson regression was used to compare fracture rates between women with and without diabetes, stratified by age at diagnosis, and adjusted for age and time-varying BMI.

resultsA total of 2251 women (18.5%) had diabetes and 3761 (30.9%) sustained at least one fracture. Compared to women without diabetes, those with diabetes had a higher fracture risk (RR 1.13; 95% CI 1.02-1.24). The excess risk varied by age at diagnosis: RR 1.61 (95% CI 1.23-2.12) for diagnosis at age 35, declining to RR 1.02 (95% CI 0.90-1.16) for diagnosis at age 60.

conclusionsDiabetes is associated with increased fracture risk, but this risk varies by age at diagnosis. Women diagnosed at younger ages face substantially higher risk, while those diagnosed later show little excess risk. Age at diagnosis may improve fracture risk assessment and inform prevention.
