Short-Term Effects of Folate Supplementation in Combination With Vitamin B6 for Treating Acute Manic Episodes in Bipolar I Disorder: A Randomized Controlled Trial.
Trial report in Brain and behavior, 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
backgroundDrug resistance poses a formidable challenge in managing acute manic episodes in bipolar I disorder, leading to suboptimal treatment outcomes. This study investigates the efficacy of folate and vitamin B6 supplementation as an adjunct to sodium valproate in improving treatment responses for patients experiencing acute mania.
methodsIn a randomized, double-blind, placebo-controlled trial, 43 patients diagnosed with bipolar I disorder presenting with acute manic episodes were enrolled. Participants were randomly assigned to three groups: one receiving folate (5 mg/day) plus vitamin B6 (80 mg/day), a second group receiving folate alone (5 mg/day), and a third group receiving placebo. Evaluations were conducted at baseline and after 3 and 6 weeks using the Mini-Mental State Examination (MMSE) and the Young Mania Rating Scale (YMRS).
resultsAll groups demonstrated significant clinical improvements after the treatment period; however, the trends in MMSE scores showed no significant differences (p = 0.068). Notably, the reduction in YMRS scores significantly varied across groups (p < 0.001, effect size = 0.342), with the folate group demonstrating a significantly greater decrease compared to both the folate/B6 (p = 0.003) and placebo groups (p < 0.001). Recovery rates revealed that 80% of patients receiving folate showed over a 50% decrease in YMRS scores after 3 weeks, markedly higher than the other groups (p = 0.001).
conclusionsOur findings support the short-term use of folate as a beneficial adjunct in treating acute manic episodes in bipolar I disorder. However, the addition of vitamin B6 did not yield additional advantages. These results may inform future treatment guidelines targeting acute mania in bipolar disorder, advocating for folate supplementation as a potential strategy to enhance therapeutic outcomes.
