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
purposeTo investigate the prevalence and clinical characteristics of Charles Bonnet Syndrome (CBS) in patients referred for bilateral cataract surgery.
methodsThis prospective, cross-sectional clinical trial included 391 patients attending cataract assessment at a single-center tertiary cataract clinic. After clinical examination, participants were screened for presence of visual hallucinations (VHs). Participants experiencing complex VHs were further questioned regarding characteristics of their hallucinatory experiences to properly determine if they were attributable to CBS. CBS was defined as complex visual hallucinations with retained insight, no medical history or medication known to cause hallucinations and not limited to hypnagogic or hypnopompic states (hallucinations happening shortly before falling asleep and/or shortly after waking up).
resultsNineteen (4.9%) patients experienced complex VHs. Of these, 11 (2.8%) were diagnosed with CBS while 8 (2.1%) had complex hypnagogic and/or hypnopompic VHs. Multivariable logistic regression analysis identified lower best-corrected visual acuity (BCVA) in the better seeing eye as a significant predictor of CBS. When excluding participants with a BCVA>0.3, prevalence of complex VHs rose to 10.0%. Three of the patients with CBS (27.3%) had ocular comorbidities: two had exudative age-related macular degeneration (AMD), and one had drusenoid AMD. In the overall cohort, twenty-four patients (6.1%) reported prior knowledge of CBS.
conclusionCBS was observed in a clinically relevant minority of cataract patients requiring bilateral surgical intervention. Given the high prevalence of cataract among the elderly, this study highlights the importance of healthcare personnel being aware of CBS and other complex VHs and their potential consequences for cataract patients.
