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
purposeThe aim of this study was to compare retinal and optic disc functions as well as vascular structures in dominant eyes (DE) and non-dominant eyes (NDE) among healthy adults using pattern electroretinogram (PERG), optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) tests.
methodsSeventy-two eyes of 36 healthy subjects with bilateral visual acuity of 1.0 were included. Parameters such as intraocular pressure (IOP), cycloplegic spherical equivalent value (SE), PERG, retinal nerve fiber layer (RNFL) thicknesses and OCTA measurements were evaluated. Ocular dominance was determined using the hole-in-the-card test.
resultsOf the participants, 67% were female, with a median age of 28 (min-max.18-35) years. Right eye dominance was observed in 61.2% of cases, while left eye dominance was seen in 38.8%. There was no significant difference in refractive values between eyes with right and left eye dominance (0.60 ± 0.40 and 0.41 ± 0.28, p = 0.42). The dominant eyes showed significantly higher P50 amplitude (10.2 µV vs. 9.2 µV, p = 0.003) and shorter peak time (47.9 ms. vs. 48.6 ms, p = 0.01) when compared to the nondominant eyes. There were comparable values in the peak times and amplitudes of the N95 component between the dominant and nondominant eyes. The RNFL layer was thicker on average (p, 0.001) as well as in the nasal and inferior quadrants of the dominant eyes (p < 0.05). OCTA analysis revealed no significant differences in the peripapillary and macular capillary vascular densities between dominant and nondominant eyes (p > 0.05), except for the deep whole capillary density in the macula, which was significantly higher in the dominant eyes (p = 0.02).
conclusionOur results indicate the existence of functional and structural relationships related to ocular dominance. Future studies provide further insights into ocular dominance and its relationship with eye structure.
