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
objectiveThis study compared the binocular and accommodative efficiency of young adults with myopic isometropia versus myopic anisometropia, difference spherical equivalent refraction (SER) ≥ 1.00 diopter (D), when corrected with ophthalmic versus contact lenses.
methodsSeventy-two participants were categorized into isometropic (n = 36; age 21.92 ± 3.21 years) and anisometropic (n = 36; age 21.44 ± 2.62 years) myopia groups. Binocular and accommodative parameters were clinically evaluated under both ophthalmic and contact lens correction.
resultsOphthalmic lens correction produced no significant differences (p > 0.05) in binocular visual efficiency between the two groups. Conversely, contact lens correction elicited distinct alterations in accommodative and vergence profiles. Myopic anisometropia showed a highly significant increase in accommodative lag when using contact lenses (p < 0.001) and increased negative relative accommodation (p = 0.007) compared to ophthalmic lenses. Furthermore, contact lenses amplified the fusional divergence demand to compensate for esophoria, thereby diminishing the near negative fusional vergence reserve (p = 0.012). Notably, contact lens wear was associated with better stereoacuity compared to ophthalmic lenses, which suggests a potential functional advantage in stereopsis for higher degrees of anisometropia, though this warrants further exploratory validation.
conclusionIn conclusion, while contact lenses distinctly alter accommodative and vergence dynamics, they may offer functional advantages in stereopsis for higher degrees of anisometropia. These comparative insights provide valuable clinical guidance for selecting refractive correction modalities to support specific binocular functions and stereoscopic performance.
