The Role of Serum Vitamin and Mineral Levels in Benign Essential Blepharospasm: A Comparative Study.
Article in Beyoglu eye journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objectives: This study aims to compare serum levels of folic acid, Vitamin B12, 25-hydroxy (OH) Vitamin D, calcium (Ca), zinc (Zn), phosphorus, and magnesium (Mg) between patients with benign essential blepharospasm (BEB) and healthy controls and to examine their associations with disease severity and frequency. Methods: A retrospective study was conducted on 20 patients with BEB (13 females, 7 males) and 25 healthy controls (15 females, 10 males) from our clinic. Serum levels of folic acid, Vitamin B12, 25-OH Vitamin D, Ca, phosphorus, Mg, and Zn, as well as ophthalmologic examination results, were analyzed. BEB severity and frequency were assessed using the Jankovic Rating Scale (0-4). Results: Serum levels of Vitamin B12, folic acid, Zn, Ca, phosphorus, and Mg were within normal limits for both groups. However, serum Vitamin D levels were below normal in both groups. No significant differences were found between the BEB and control groups regarding serum Vitamin B12, 25-OH Vitamin D, Ca, phosphorus, Mg, and Zn levels (p>0.05). Notably, serum folic acid levels were significantly lower in the BEB group compared to controls (6.19±2.75 vs. 8.95±4.10, p=0.011). In addition, a significant negative correlation was observed between serum folic acid levels and Jankovic severity (r=-0.378, p=0.011) and frequency scores (r=-0.392, p=0.008). Conclusion: These findings suggest that folic acid may play a role in BEB pathogenesis. Further studies are needed to explore the underlying mechanisms and potential benefits of micronutrient supplementation in BEB management.
