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
introductionDiabetic foot disease is one of the most severe complications of diabetes mellitus, contributing substantially to hospitalization, lower limb amputation, and premature mortality. This study evaluated the associations of glycemic control (glycated hemoglobin [HbA1c]), age, and sex with diabetic foot risk and ulceration among patients attending a tertiary diabetes center in Qassim, Saudi Arabia.
methodsThis retrospective cross-sectional study included a census sample of 710 eligible electronic medical records of patients with a confirmed diagnosis of diabetes mellitus and a documented diabetic foot assessment between January 2022 and December 2024. No a priori sample size calculation was performed. The primary outcome was at-risk diabetic foot status (International Working Group on the Diabetic Foot category ≥ 1), and the secondary outcome was active foot ulceration. Multivariable logistic regression was used to identify factors independently associated with each outcome.
resultsThe mean age was 57.6 ± 14.0 years; 337 patients (47.5%) were male and 373 (52.5%) were female, and 93.2% had type 2 diabetes mellitus. At-risk diabetic foot status was present in 53.2% of patients, and active foot ulceration was present in 3.0%. Ulcer prevalence increased across HbA1c categories (1.9%, 2.6%, and 6.3%), and at-risk status increased with age (39.6-62.1%). Older age (odds ratio [OR] = 1.028; 95% confidence interval [CI] 1.016-1.039; P < 0.001) and male sex (OR = 1.403; 95% CI 1.036-1.901; P = 0.029) were independently associated with the at-risk status. HbA1c was not independently associated with at-risk status (P = 0.422) or ulceration (P = 0.077).
conclusionsUlcer prevalence increased with poorer glycemic control; however, the adjusted HbA1c-ulceration association was not significant in the primary model. Key confounders were unavailable in the dataset, including diabetes duration, neuropathy and peripheral arterial disease severity, and renal function. Therefore, residual confounding cannot be excluded, and HbA1c's role in diabetic foot risk should not be discounted. These findings suggest that diabetic foot screening and preventive care should be tailored to specific age and sex groups, involving multiple healthcare disciplines.
