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 Diabetic foot ulcer (DFU) is a major complication of diabetes with many identified risk factors. These include poor control of diabetes, cardiovascular disease, smoking, and end-stage kidney disease. This study aims to shed light on the micronutrient status of diabetic patients and its effect on DFU, particularly, the association between vitamin B12 deficiency and DFU. Methodology This retrospective case-control study included adults in Buraydah who were at least 18 years old and had type 2 diabetes mellitus. Data were obtained from the electronic files of the patients who visited the diabetes center from January 2018 to August 2023 and were analyzed using SPSS version 27.0.1 (IBM Corp., Armonk, NY, USA). Results The research involved 221 participants, with 114 controls (individuals with diabetes but no DFU), and 107 cases (individuals with diabetes affected by DFU). Vitamin B12 levels varied, with 79.2% falling within the normal range of 187-883 pg/mL. The average age of cases (58.5 years, SD = 11.3) was notably higher than that of controls (54.1 years, SD = 14.1). Glycated hemoglobin levels were significantly higher in cases (8.7, SD = 2.0) compared to controls (7.6, SD = 2.2) (p < 0.001). Regarding physical activity, cases showed a significantly higher percentage of inactivity (62.1%) compared to controls (39.1%) (p = 0.046). Neuropathy exhibited a significant association with ulcer development, with 59.1% of cases having neuropathy compared to 23.5% of controls (p < 0.001). Furthermore, complications such as dry foot and fissures (60.0% vs. 6.3%), Charcot joint (36.8% vs. 12.2%), and foot trauma (40.9% vs. 3.9%) were significantly more prevalent in cases compared to controls (p < 0.001 for all). Conclusions The significant associations observed with advanced age, uncontrolled diabetes, longer diabetes duration, neuropathy, and specific foot complications underscore the multifactorial nature of ulcer development. The normal levels of vitamin B12 in most patients reflect no positive impact of normalized vitamin B12 levels on DFU. However, further observational studies with multiple vitamin B12 readings over a longer period are needed to establish its association with DFU development.
