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

introductionThe aim of this study was to investigate the magnitude and quadrantal distribution of angle kappa in patients with cataracts and high myopia (axial length ≥ 26 mm).

methodsA total of 2485 patients with cataracts and high myopia and 354 patients with cataracts without high myopia (axial length < 26 mm) were included in this study. The location and value of angle kappa were determined using an Oculus Pentacam HR. An angle kappa distance exceeding 0.5 mm was defined as a large angle kappa distance.

resultsIn high myopic eyes, multivariable linear regression analysis revealed that a larger angle kappa distance was significantly associated with longer axial length (standardized regression coefficient [β] = 0.24), narrower white-to-white (β =  -0.08), lower keratometry (β =  -0.08), higher corneal astigmatism (β = 0.06), and older age (β = 0.06) (all P < 0.01). The axial length cutoff point with the maximum Youden Index indicating the presence of a large angle kappa distance was 30 mm (area under the curve = 0.64). In high myopic eyes, the most common regions of angle kappa relative to the pupillary axis were the temporal-superior (40%) and temporal-inferior (26%) quadrants. However, in non-high myopic eyes, the most frequent regions were the nasal-superior (31%) and nasal-inferior (31%) quadrants.

conclusionsAn axial length of ≥ 30 mm is a risk factor for the presence of an angle kappa distance greater than 0.5 mm. In high myopic eyes, the most common location of angle kappa is the temporal-superior quadrant relative to the pupil center.
