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
Purpose: To assess the agreement between noncycloplegic autorefraction and subjective refraction across age groups and refractive error types in a large real-world clinical study using clinically meaningful thresholds for spherical and astigmatic components. Methods: This retrospective study analyzed 827 eyes from patients aged 7-85 years examined between May 2023 and January 2025. Objective refraction was measured using a KR-1 autorefractor (Topcon, Tokyo, Japan), followed by standard subjective refinement. Spherical equivalent (SE), cylinder power (CP), and power vectors (J0, J45) were calculated using Fourier vector analysis. Agreement was evaluated using absolute differences and predefined clinical criteria (SE ± 0.50 D; CP ± 0.25 D; axis ≤ 10° when CP ≥ 0.50 D). Comparisons were performed across three age groups (7-21, 22-49, ≥ 50 years) and refractive subgroups. Results: SE agreement was high across all ages, with 90.8% of eyes within ±0.50 D. J0 demonstrated a progressive shift from with-the-rule to against-the-rule astigmatism with age, whereas J45 remained near zero. CP differences were generally small but slightly larger in older adults. Axis deviations > 10° occurred in 27.2% of eyes, predominantly when CP was low (mean 0.51 ± 0.42 D), suggesting limited visual impact in most cases. Conclusions: Noncycloplegic autorefraction has been demonstrated to exhibit a high degree of agreement with subjective refraction for SE in both adolescents and adults. The astigmatic shifts that occurred with age were minimal and had only a limited effect on clinical outcomes. Subjective refinement remains a critical component in the precise determination of axes, particularly in cases of hyperopia, mixed astigmatism, and in eyes of advanced age. Future studies that include hyperopic children and young patients requiring cycloplegia would be valuable in extending these findings to a broader range of pediatric populations.
