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

backgroundPrevious studies have reported inconsistent findings regarding the relationship between socioeconomic status (SES) inequalities and comorbidities in patients with diabetes mellitus (DM). This systematic review and meta-analysis aims to evaluate, for the first time, the association between SES inequalities and comorbidities in individuals with DM.

methodsTwo independent investigators searched the PubMed, Embase, Scopus, Web of Science and Google Scholar databases using MeSH terms to identify studies that investigated the association between SES and DM comorbidities up to 15 December 2025. This systematic review followed the PRISMA 2020 checklist. Heterogeneity among studies was assessed using Cochran's Q and I

resultsThirteen studies involving 757,599 DM patients were included. A pooled estimate of 13 studies showed that low SES, compared with moderate or high SES, was significantly associated with an increased probability of DM comorbidities (OR: 1.43; 95% CI: 1.30, 1.59; I

conclusionThe chance of developing type 2 diabetes comorbidities in patients with T2DM of low SES, especially in women, may be higher than in patients with middle and high SES. Improvements in healthcare systems and interventions to reduce inequalities in SES in patients with type 2 diabetes, especially in patients with low SES, are recommended.
