Low contrast visual acuity in healthy adults: Impact on non-pathologic myopia.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Increase in myopia is a social issue worldwide. However, whether non-pathologic myopia with normal best-corrected visual acuity (BCVA) exhibits differences in visual ability is not well-documented. Data of 43 healthy eyes in 43 participants (52.8 ± 6.07 years) including 13 (30.2%) males who underwent eye medical checkups at Fujita Medical Innovation Center, Tokyo were retrospectively analyzed. Eyes with general BCVA 0 in logMAR or better and without histories of ocular diseases and surgeries were included. Mean low-contrast visual acuity (LCVA) measured using grey-scale optotypes with best correction was 0.17 ± 0.13 (range, -0.079-0.53; median, 0.15). LCVA was correlated with age (r = 0.2634, 95% confidence interval [CI] -0.040-0.522, P = 0.039). Eyes with LCVA better than 0.15 was associated with uncorrected visual acuity (OR, 43.425; 95%CI, 3.729-1250.027; P = 0.010), subjective spherical equivalent (OR, 1.761; 95%CI, 1.255-2.776; P = 0.004), subjective spherical power (OR, 1.616; 95%CI, 1.186-2.433; P = 0.008), and axial length (OR, 0.550; 95%CI, 0.293-0.951; P = 0.032) after adjusted for age and sex. Mean LCVA of less myopic eyes with spherical equivalent > -3.0 diopters was 0.12 ± 0.10 (median, 0.10), and that of more myopic eyes was 0.23 ± 0.14 (median, 0.22) (P < 0.001). Non-pathological myopic eyes exhibited worse LCVA under best correction and had a risk of worse visual ability.
