Does the Combination of Abdominal Obesity and Vitamin D Deficiency Increase the Risk of Death in Individuals Aged 50 or Older? Evidence From the ELSA Study.

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
aimsDespite the known association between abdominal obesity (AO) and vitamin D deficiency, it remains unclear whether this combination is associated with higher mortality risk. We investigated whether the coexistence of AO and vitamin D deficiency elevates the risk of death. MATERIALS AND
methodsFive thousand, five hundred twenty participants from the ELSA Study, aged ≥ 50 years, were followed for 6 years. AO was defined by waist circumference (> 102 cm for men and > 88 cm for women). Vitamin D levels, measured via serum 25-hydroxyvitamin D [25(OH)D] concentrations, were categorised as sufficient (≥ 50 nmol/L), insufficient (30-50 nmol/L), and deficient (< 30 nmol/L). At baseline, participants were classified according to AO (non-abdominal obesity [NAO] and AO) and 25(OH)D status (sufficiency [VDS], insufficiency [VDI], and deficiency [VDD]), creating six groups: NAO/VDS, NAO/VDI, NAO/VDD, AO/VDS, AO/VDI, and AO/VDD. Cox regression models adjusted for sociodemographic, behavioural, and clinical characteristics estimated mortality risk.
resultsThe NAO/VDI and NAO/VDD groups were associated with a 91% (HR = 1.91; 95% CI: 1.37-2.66) and 81% higher risk of death (HR = 1.81; 95% CI: 1.25-2.62), respectively. The AO/VDS and AO/VDI groups had a 47% (HR = 1.47; 95% CI: 1.02-2.14) and 50% higher mortality risk (HR = 1.50; 95% CI: 1.01-2.23), respectively, compared to the NAO/VDS group. The highest mortality risk was observed in the AO/VDD group (HR = 2.23; 95% CI: 1.50-3.33).
conclusionsAO combined with 25(OH)D deficiency increases mortality risk in older adults. Early identification and management of these conditions could reduce this risk.
