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

purposeTo compare the changes in subfoveal choroidal thickness (SFChT) in myopic children treated with 0.01% atropine, orthokeratology (OK), or their combination in myopic children, and to study the connection between increase in SFChT and axial length (AL) elongation.

methodsThis is a prospective, randomized, controlled study. A total of 67 children were included; 22 patients were randomly assigned to the SA group (patients with spectacles and 0.01% atropine), 24 patients were randomly assigned to the OK group (OK), and 21 patients were randomly assigned to the OKA group (OK and 0.01% atropine). Comprehensive ophthalmologic examinations were performed at baseline, 1 month, 6 months, and 12 months.

resultsAfter 1 month, SFChT increased by 5.41 ± 1.65 μm in the SA group, 17.46 ± 2.79 μm in the OK group, and 20.19 ± 2.18 μm in the OKA group (P = 0.00), whereas AL was not significantly increased. After 12 months, the changes of SFChT were not increased significantly compared with that at 1 month; AL increased by 0.20 ± 0.03 mm in the SA group, 0.28 ± 0.03 mm in the OK group, and 0.14 ± 0.03 mm in the OKA group (P = 0.00). The change in SFChT at 12 month was negatively correlated with the change in AL at 12 months.

conclusionThe control of AL elongation was better in SA group than OK group. The increase in SFChT was best in OKA group, followed by OK group, and the changes were significant after only 1 month. In addition, the increase in SFChT may influence AL elongation and myopia progression.
