Visual training system 4: a promising adjuvant therapy for ocular accommodative function and visual acuity improvement in refractive amblyopia patients.

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
objectiveTo evaluate the therapeutic effects of Visual Training System 4 (VTS4) as an adjunctive therapy for patients with refractive amblyopia.
methodA total of 82 patients with refractive amblyopia (142 eyes) treated at the Zhongshan Ophthalmic Center of Sun Yat-sen University, were enrolled and divided into two groups based on the treatment protocol. The control group included 40 patients (68 eyes) who received conventional comprehensive treatment, while the observation group was comprised of 42 patients (74 eyes) treated with VTS4 in addition to conventional therapy. The therapeutic effects, best-corrected visual acuity (BCVA), spherical equivalent (SE), ocular accommodative function, and ocular convergence were compared between the two groups.
resultsThe total effective rate of visual improvement in the observation group was 86.49%, significantly higher than 66.18% in the control group. BCVA at 3 and 6 months was superior in the observation group compared to the control group (P < 0.05). At 6 months, the normal rate of binocular fusion images in the observation group was 94.59%, higher than 76.47% in the control group. The observation group showed greater improvement in accommodative flexibility and amplitude, and lower accommodative lag compared to the control group. Improvements in negative relative accommodation, positive relative accommodation, and near point of convergence were also more pronounced in the observation group (all P < 0.05). No significant differences were observed in SE, axial length, or corneal curvature within or between the groups before and after treatment (all P > 0.05).
conclusionVTS4, as an adjunctive therapy for refractive amblyopia, significantly improves visual acuity, enhances accommodative and convergence functions, and demonstrates strong clinical applicability.
