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 measure accommodative performance as a function of refractive error in very young children.

methodsThis was a prospective study of accommodation lag in multiethnic typically developing children ages 5 to 24 months. Accommodation lag was measured by means of a modified bell retinoscopy technique. Refraction was measured by cycloplegic retinoscopy, and right and left eye results were averaged. The study compared accommodative performance to cycloplegic spherical equivalent and astigmatic refractive error.

resultsAnalysis of data from 189 of 203 subjects revealed that larger lags and lower gain of the accommodative response were more common in younger children, although most children of all ages accommodated well, with 95% having lags <1.25 D. Larger accommodation lags were associated with greater spherical equivalent refractive error, although only with hyperopia ≥4.0 D were lags ≥1.25 D observed in a majority of children. Larger lags in the more hyperopic meridian were seen with increasing hyperopic with-the-rule astigmatism, but lag in the more hyperopic meridian varied little with the amount of myopic or mixed astigmatism.

conclusionsMost 5- to 24-month-old children accommodate well over a range of moderate hyperopic refractive errors, but hyperopia ≥4.0 D is rarely associated with normal accommodative performance. Hyperopic and mixed or myopic astigmatic children show different patterns of accommodation, which may explain the patterns of visual acuity deficits seen in these children.
