1 · What the graph read from it

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.

2 · The registry

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

Objective: To evaluate 12-month myopia control efficacy of diffusion optics technology (DOT) spectacle lenses in a Chinese population (CATHAY study). Design: Interim analysis of 6-month and 12-month data from a 24-month, randomized controlled clinical trial across 5 Chinese hospital sites, evaluating DOT spectacle lenses versus control standard single-vision (SV) spectacle lenses. Participants: One hundred ninety-five myopic children aged 6-13 years were enrolled across 5 sites in China. Participants were dispensed DOT lenses in a 2:1 ratio versus SV. Methods: Participants were randomized to DOT or SV spectacles. Axial length (AL) and cycloplegic spherical equivalent refraction (cSER) were measured at baseline, 6 months, and 12 months. Main Outcome Measures: Twelve-month changes in AL and cSER from baseline. Results: One hundred eighty-six children (DOT 128, SV 58) completed the 12-month visit (modified intent-to-treat cohort) with a mean age at prerandomization eligibility visit (baseline) of 9.6 ± 1.8 years. No severe adverse events were observed in either group. For DOT wearers, the mean observed change ± standard deviation in AL was 0.09 ± 0.22 (95% confidence interval [CI]: 0.05 to 0.13), and cSER change was -0.16 ± 0.51 D (95% CI: -0.25 to -0.07). For the SV group, mean observed change from baseline at 12 months for AL was 0.35 ± 0.19 mm (95% CI: 0.30-0.40), and cSER change was -0.64 ± 0.42 D (95% CI: -0.76 to -0.53). The least squares mean differences (±standard error) in AL elongation and cSER progression were significantly lower for DOT vs. SV at 12 months. The difference in AL change between DOT and SV was -0.26 ± 0.03 mm ( Conclusions: The 12-month interim results from this ongoing trial demonstrate the effectiveness of DOT spectacles for reducing myopic progression and axial elongation in Chinese children. A lens design based on the modulation of contrast on the retina works favorably for young Chinese children.
