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

backgroundTo evaluate the prognostic performance of the single-sample confirmatory definition of undiagnosed diabetes on outcomes, including hypertension, chronic kidney disease (CKD), cardiovascular disease (CVD), and mortality, in the Tehran Lipid and Glucose Study cohort.

methodsAmong 6712 participants (3682 women) aged ≥ 30 years not on glucose-lowering medication, unconfirmed undiagnosed diabetes was defined as either fasting plasma glucose (FPG) ≥ 7 mmol/L or 2-h postload glucose (2-h PG) ≥ 11.1 mmol/L, whereas confirmed undiagnosed diabetes required both. Multivariable Cox models estimated hazard ratios (HRs) and 95% confidence intervals (CIs) for each outcome.

resultsAt baseline, 3.6% and 3.3% of participants had confirmed or unconfirmed undiagnosed diabetes, respectively. During a median follow-up of over 10 years, both unconfirmed and confirmed undiagnosed diabetes were associated with a higher risk of developing treated diabetes, with HRs (95% CI) of 7.73 (6.35-9.44) and 17.30 (14.32-20.83), respectively. Confirmed undiagnosed diabetes was further associated with incident CKD (1.33 [1.02-1.73]), hypertension (1.26 [1.00-1.60]), first CVD (1.40 [1.01-1.93]), and hard CVD (1.65 [1.04-2.61]), whereas the association with all-cause mortality did not reach statistical significance (1.50 [0.96-2.33], p = 0.07). Unconfirmed undiagnosed diabetes was only associated with treated diabetes and first CVD (1.53 [1.11-2.12]). Isolated FPG and 2-h PG elevations showed similar risks for treated diabetes (9.00 [6.26-13.00] and 7.40 [5.92-9.24], respectively), but only isolated FPG was significantly associated with first CVD (2.55 [1.50-4.31]) and hard CVD (2.43 [1.06-6.00]), comparable with confirmed undiagnosed diabetes.

conclusionsConfirmed undiagnosed diabetes was associated with a higher risk of cardiovascular and renal outcomes. The unconfirmed undiagnosed phenotype shared a similar CVD risk with confirmed diabetes but had a 50% lower risk of treated diabetes, with a stronger association observed for isolated FPG elevation than for isolated 2-h PG.
