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: Ocular adverse events associated with cisplatin and capecitabine are uncommon, and bilateral optic disc edema with papillophlebitis-like features has rarely been reported. We describe a case of bilateral optic disc edema with papillophlebitis-like features following combined cisplatin and capecitabine chemotherapy in a patient with squamous cell carcinoma of the anal canal. We discuss the differential diagnosis, possible mechanisms, and clinical course in the context of the existing literature. Case presentation: A 50-year-old woman with squamous cell carcinoma of the anal canal received pelvic radiotherapy (28 fractions) combined with four cycles of cisplatin and oral capecitabine. Sixteen days after the final cycle of chemotherapy, she developed painless bilateral blurred vision. Fundus examination revealed bilateral optic disc edema and hyperemia, peripapillary flame-shaped hemorrhages, and dilated retinal veins. Fundus fluorescein angiography demonstrated leakage from the optic disc vasculature, while optical coherence tomography(OCT) showed bilateral thickening of the peripapillary retinal nerve fiber layer. Comprehensive systemic work-up, including complete blood count, inflammatory markers, tumor markers, a paraneoplastic antibody panel, contrast-enhanced brain magnetic resonance imaging, and multidisciplinary consultation, revealed no alternative systemic, neurologic, or paraneoplastic explanation. Intracranial hypertension, optic neuritis, and non-arteritic anterior ischemic optic neuropathy (NAION) were considered less likely based on the overall clinical findings. No systemic glucocorticoids were administered, and the patient was managed with close observation. At the two-month follow-up, best-corrected visual acuity had improved to 1.2 in both eyes, with complete resolution of the optic disc edema on fundus examination and OCT. Discussion: The temporal association with chemotherapy, bilateral presentation, papillophlebitis-like fundus findings, and spontaneous resolution after completion of treatment suggest a possible chemotherapy-associated toxic or vascular reaction. Cisplatin-related endothelial toxicity and capecitabine-associated vasospasm may be potential mechanisms. However, a direct causal relationship cannot be established from a single case.
