Association between weight-adjusted-waist index and serum ferritin in patients with type 2 diabetes.
Article in Asia Pacific journal of clinical nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND AND
objectivesTo investigate the correlation between weight-adjusted-waist index (WWI), a novel obesity index, and serum ferritin (SF) level in patients with type 2 diabetes mellitus (T2DM), and the association between WWI and the prevalence of hyperferritinemia. METHODS AND STUDY
designA total of 943 patients with T2DM were divided into three groups based on WWI tertile levels. Disparities in SF levels and the prevalence of hyperferritinemia were compared among these groups. The correlations among WWI, SF levels, and hyperferritinemia were analyzed in patients with T2DM.
resultsAs WWI tertile levels increased, SF levels tended to increase (p for trend <0.01). A statistically significant positive correlation was observed between the WWI and SF levels (R = 0.263, p < 0.001). After adjusting for confounders by multiple linear regression, a significant positive correlation was maintained between the WWI and SF levels [β = 0.194, 95% CI (49.914, 112.120)], p < 0.01]. Binary logistic regression analysis revealed a positive association between the WWI and the likelihood of hyperferritinemia, with a notably stronger correlation observed in females compared to males [OR = 3.248, 95% CI (2.027, 5.204), p < 0.01 vs. OR = 2.091, 95% CI (1.432, 3.054), p < 0.01].
conclusionsAlong with increasing WWI, SF levels gradually increased in patients with T2DM. The WWI exhibited a positive correlation with SF levels and hyperferritinemia, more significantly in female patients.
