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
purposeThis study evaluated the efficacy of spectacle lenses with highly aspherical lenslets (HALs) for myopia control in clinical practice.
methodsA retrospective cohort study with propensity score matching (PSM) was conducted using patients from the Eye Hospital, Wenzhou Medical University from July 1, 2020 to March 15, 2023. Participants wore either HALs or single-vision lenses (SVL). PSM was used to balance confounding factors between groups. Efficacy was assessed by comparing myopia progression (non-cycloplegic refractive error) and axial length (AL) elongation between the two groups.
resultA total of 3419 HALs and 10,846 SVL users aged 3-18 years were included (mean SER: -2.92 ± 1.82 D, range +0.50 to -9.00 D). After PSM, 2050, 1524, 807 and 433 pairs were retained in the 0.5, 1, 1.5 and 2 year sub-datasets, respectively. Additionally, a sub-dataset containing AL measurement from 406 pairs at 1 year was analysed. In the matched dataset without AL, the HAL group exhibited significantly slower myopia progression both at 1 year (-0.33 vs. -0.63 D) and 2 years (-0.68 vs. -1.10 D) compared with the SVL group. Furthermore, in the 1-year matched dataset that included AL, the HAL group showed significantly less AL elongation (0.19 mm) and myopia progression (-0.37 D) than the SVL group (0.37 mm, 0.69 D). Subgroup analysis indicated that the reduction in myopia progression was evident amongst children aged 3-14 years with low and moderate myopia. However, no significant difference was observed in the 15-18 year-old subgroup with low-to-moderate myopia or in the high myopia subgroup (all p > 0.05).
conclusionThis real-world study found that wearing HALs effectively reduced myopia progression and axial elongation in children aged 3-14 years with low-to-moderate myopia. However, the efficacy of HALs was inconclusive in children aged 15-18 years and limited in those with high myopia.
