Assessing the neurological impact of vitamin B12 deficiency among the population of Riyadh, Saudi Arabia.

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: Vitamin B12 (cobalamin) deficiency can cause anemia, peripheral neuropathy, visual impairment and irreversible neurological damage. Little is known about public awareness of these neurological effects in Saudi Arabia. This study assessed awareness of the neurological impact of vitamin B12 deficiency among adults in Riyadh, Saudi Arabia. Methods: We conducted a population-based cross-sectional survey in Riyadh between March and April 2024. Adults aged ≥18 years were recruited via social media. Individuals affiliated with the health sector were excluded to reduce bias. A validated questionnaire assessed sociodemographics, awareness of vitamin B12, dietary sources, deficiency symptoms and prevention. Descriptive statistics and chi-square tests were used ( Results: Of 1,337 participants, 23 were excluded, leaving 1,314 respondents; 62.3% were female. Most (65.6%) recognized the importance of vitamin B12, 38.7% identified a dietary source, and 29.9% used supplements. Awareness of the neurological consequences of deficiency was reported by 63.4%. Women showed greater knowledge than men ( Conclusion: Overall awareness of vitamin B12 and its neurological consequences was moderate. However, knowledge of dietary sources and prevention strategies was limited, and misperceptions (e.g., fruits and vegetables as sources) were common. Targeted public-health education and nutritional counseling are needed to address these gaps.
