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
The purpose of this study was to assess the retinal relative peripheral refraction (RPR) in children with low myopia and pre-myopia, and investigate the differences in RPR using multispectral refraction topography (MRT). Ninety-five children were enrolled in the Department of Ophthalmology, Jinshan Hospital affiliated to Fudan University. MRT could measure total RPR (TRPR) of the 53° range centered on macular fovea. TRPR divided into four quadrants: superior RPR (RPR-S), inferior RPR (RPR-I), temporal RPR (RPR-T) and nasal RPR (RPR-N). The MRT analysis report also showed RPR in the visual field of 15° (RPR-15), 30° (RPR-30) and 45° (RPR-45) centered on the macular fovea, respectively. RPR-(15-30), RPR-(30-45) and RPR-(15-45) were calculated. TRPR (R = - 0.264, P = 0.010), RPR-I (R = - 0.261, P = 0.011), RPR-T (R = - 0.240, P = 0.019), RPR-45 (R = - 0.211, P = 0.040), RPR-(30-45) (R = - 0.232, P = 0.023) and RPR-(15-45) (R = - 0.243, P = 0.018) were negatively correlated with spherical refraction. Spherical equivalent of low myopia group was significantly less than pre-myopia group (- 1.18 ± 0.57 D vs. 0.13 ± 0.31 D, P < 0.001) whereas axial length of low myopia group was significantly longer than pre-myopia group (24.14 ± 0.70 mm vs. 23.35 ± 0.60 mm, P < 0.001). TRPR of low myopia group and pre-myopia group was 0.52 ± 0.62 D and 0.32 ± 0.41 D, respectively, without sigficant difference (P = 0.075). All the RPRs were hyperopia in the children with low myopia and pre-myopia, except for RPR-T in pre-myopia group. RPR-I in low myopia group was significantly larger than that in pre-myopia group (0.42 ± 0.72 (95% CI 0.22, 0.62) D vs. 0.04 ± 0.67 (95% CI - 0.17, 0.25) D, P = 0.010). In conclusion, RPRs become more hyperopia with the changing trend from pre-myopia to myopia. Children with low myopia and pre-myopia have relative peripheral hyperopia. Furthermore, children with low myopia have larger relative peripheral hyperopia compared with pre-myopia.
