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: Visual disturbances are a common and often debilitating complication following stroke, significantly impairing patients' functional independence and quality of life. Among various neuroprotective agents, Citicoline (cytidine-5'-diphosphocholine) has demonstrated multifaceted mechanisms of action, including modulation of phospholipid metabolism, reduction of oxidative stress, and enhancement of dopaminergic and cholinergic neurotransmission. These properties suggest potential benefits in promoting visual recovery post-stroke. Objectives: To analyze the effect of Citicoline administration on the improvement of visual impairment in patients with a history of stroke at Prof. Dr. Chairuddin Panusunan Lubis Hospital, University of Sumatera Utara, and its network hospitals. Methods: This quasi-experimental study employed a pre- and post-intervention design involving 30 post-stroke patients who received 1,000 mg of oral Citicoline daily for 30 consecutive days. Visual function was evaluated through standard ophthalmological assessments, including visual acuity (logMAR), visual field analysis using the Humphrey Field Analyzer, contrast sensitivity (Pelli-Robson chart), and color sensitivity test (Farnsworth Munsell D-15 test), both before and after treatment. Results: Post-treatment analysis revealed no statistically significant improvement in visual acuity or visual field parameters ( Conclusion: Oral Citicoline supplementation over a 30-day period appears to exert a beneficial effect specifically on contrast sensitivity in stroke patients with visual dysfunction, while its impact on visual acuity, visual fields, and color perception remains inconclusive. Further research involving combinations with other neuroprotective agents, larger sample sizes, or longer intervention durations is needed to confirm these findings and to explore the potential benefits of Citicoline more comprehensively.
