Effects of Three-Wavelength-Cut Lens on Cone Contrast Sensitivity.

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
The purpose of this study was to quantitatively evaluate the effects of a three-wavelength-cut (TWC) lens, a type of wavelength-control lens, on cone contrast sensitivity in healthy adults using ColorDx CCT-HD (KONAN MEDICAL, Inc.). TWC lenses selectively attenuate light at wavelengths below approximately 420 nm, as well as around 460 and 585 nm. Fifteen healthy adults (mean age, 39.7 ± 9.0 years) were examined under two conditions: full refractive correction alone and full refractive correction with the TWC lens. Cone contrast sensitivity scores corresponding to long-wavelength-sensitive cones (L-cones), middle-wavelength-sensitive cones (M-cones), and short-wavelength-sensitive cones (S-cones) were measured. The L-cone-axis score was treated as the primary outcome, with the M- and S-cone-axis analyses considered exploratory. Paired comparisons were supplemented with a two-way repeated-measures ANOVA using lens condition and cone axis as within-subject factors. The primary L-cone analysis showed a significantly higher contrast sensitivity score with the TWC lens than without it (
