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 relationship between visual functioning as measured by the National Eye Institute 25-Item Visual Function Questionnaire (VFQ-25) and geographic atrophy (GA) imaging characteristics including foveal involvement, multifocal lesions, and GA size.
methodsThis cross-sectional cohort study included patients from the University of Colorado Age-related macular degeneration (AMD) registry, enrolled between July 2014 and May 2023, who had GA in at least one eye and completed the VFQ-25 at time of study enrollment. GA size was averaged between the two eyes for each patient. General linear modeling was used to assess the association between GA imaging characteristics with the outcome of Rasch-transformed VFQ-25 scores.
resultsA total of 140 AMD patients with GA and VFQ-25 scores were included in the study. LogMAR visual acuity for the better-seeing eye of each patient was negatively associated with Rasch-transformed VFQ scores (-3.03, standard error (SE): 0.46, p < 0.0001). Foveal involvement in both eyes was significantly associated with worse Rasch-transformed scores when compared to those without foveal involvement in either eye (-1.33, SE: 0.38, p = 0.0006). Multifocal lesions in both eyes compared with unifocal lesions in both eyes had no significant difference in score (p = 0.179). GA size was significantly associated with worse VFQ-25 scores (-0.09, SE: 0.02), p < 0.0001), which did not remain significant after adjustment for LogMAR of both eyes (p = 0.137).
conclusionsWe found bilateral foveal involvement and averaged GA size were significantly associated with worse Rasch-transformed VFQ-25 scores, but these associations did not remain significant after adjustment for visual acuity. Unilateral GA was significantly associated with better scores. This study highlights the impact GA imaging characteristics and bilateral involvement have on visual functioning. KEY MESSAGES: WHAT IS KNOWN: Geographic atrophy (GA) in age-related macular degeneration negatively impacts visual functioning, and prior studies suggest that both lesion characteristics and visual acuity contribute to patient-reported outcomes.The gold-standard for Telangiectatic capillaries (TelCaps) detection is indocyanine green angiography, which is invasive and may not be readily available in all settings. WHAT IS KNEW: Bilateral foveal involvement and larger GA size were significantly associated with worse visual functioning as measured by Rasch-transformed VFQ-25 scores.Infrared reflectance imaging complemented by optical coherence tomography B-scans are effective in the detection and measurement of TelCaps, which appeared to be dynamic lesions that remodel over time. Patients with unilateral GA reported better visual functioning, underscoring the importance of preserving vision in the better-seeing eye.Eyes with DME and TelCaps with at least one year of follow-up ended up with persistent edema and stable or worse vision after injection therapy.
