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

Background and Aim: Long-term metformin use in Type 2 Diabetes Mellitus (T2DM) patients is associated with Vitamin B12 deficiency. This study aims to evaluate physicians' knowledge, attitudes, and practices regarding Vitamin B12 screening and supplementation in this context. Methods: A survey was administered to physicians across various specialties in government hospitals and primary care centers in Riyadh, Saudi Arabia, from January 2019 to January 2020. The survey assessed their knowledge, attitudes, and practices concerning Vitamin B12 deficiency screening and supplementation. Results: Of the 402 participating physicians, 94.0% (378 respondents) demonstrated sufficient knowledge about Vitamin B12 deficiency. However, 26.1% believed that Vitamin B12 supplementation does not necessitate screening. 55.7% did not prescribe Vitamin B12 prophylactically, 41.5% omitted neurological examinations in patients presenting with neuropathy, and 22.4% were unaware of the recommended Vitamin B12 supplement dose. Only 49.8% routinely screened for Vitamin B12 deficiency in symptomatic patients. Physicians with more extended years of experience showed significantly better knowledge about Vitamin B12 screening and supplementation (p<0.001). Conclusion: While most physicians were knowledgeable about Vitamin B12 deficiency and supplementation, a substantial gap in translating this knowledge into practice was observed. There is a critical need for institutional oversight to ensure adherence to American Diabetes Association (ADA) guidelines for Vitamin B12 screening and supplementation in T2DM patients on long-term metformin therapy.
