Association between delay in diabetes development and mortality in people with obesity: Up to 33 years follow-up of the prospective Swedish Obese Subjects study.
Article in Diabetes, obesity & metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
aimsLife expectancy is reduced in people with obesity and is further reduced in those with concomitant type 2 diabetes. The aim of the study was to assess whether a 2-year delay in diabetes development influences life expectancy in people with obesity. MATERIALS AND
methodsParticipants from the Swedish Obese Subjects study without diabetes at baseline and known diabetes status at the 2-year follow-up were included: bariatric surgery (n = 1471) and usual obesity care (n = 1392). Median follow-up was 26.1 years (interquartile range: 22.7-28.7 years). The Swedish Cause of Death Register, case sheets and autopsy reports were assessed to determine the direct cause of death. Analyses were adjusted for preselected risk factors: inclusion year, sex, baseline age, body mass index (BMI) and smoking.
resultsAcross both study arms, 146 participants were newly diagnosed with type 2 diabetes at the 2-year examination, whereas 2717 remained diabetes-free. Most participants diagnosed with diabetes (n = 140) were from the usual care control group. During the follow-up, there were 18.3 deaths per 1000 person-years (95% confidence interval [CI]:14.1-23.9) in the group with diagnosed diabetes at the 2-year follow-up and 10.9 deaths per 1000 person-years (95% CI:10.2-11.8) in the group that remained diabetes-free (adjusted hazard ratio [HRadj] 1.60, 95% CI: 1.19-2.15, p = 0.002). The adjusted median life expectancy in the diabetes group was 3.7 years (95% CI: 1.4-6.0, p = 0.002) shorter than in the diabetes-free group. Specifically, cardiovascular mortality was higher in the group with diabetes (adj sub-hazard ratio [sub-HR] 1.74 [95% CI: 1.09-2.77], p = 0.021).
conclusionsA 2-year delay in diabetes development may be linked to increased life expectancy, possibly due to a reduction in cardiovascular mortality. Future studies should confirm these findings.
