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 determine the effect of dilating drops on strabismus measurements in adults.

designProspective cohort study.

methodsPatients aged 18 and older with strabismus underwent a standard evaluation of ocular motility, stereopsis, and ocular alignment with alternate prism cover test by a certified orthoptist. After pupil dilation with 2.5% phenylephrine and 1% tropicamide, ocular alignment was remeasured in primary gaze at 6 meters, at 1/3 meter, and at 1/3 meter with a +3.00 by a second certified orthoptist, masked to the previous measurements. The primary outcome was the mean difference in the angle of horizontal and vertical deviations after dilation in prism diopters.

resultsA total of 55 patients were enrolled with a variety of diagnoses. For horizontal measurements the mean change was 0.54 prism diopters at 6 meters (95% confidence interval [CI] -0.36 to 1.43, P = .24), 1.67 prism diopters at 1/3 meter (95% CI -0.19 to 3.54, P = .08), and -0.05 prism diopters at 1/3 meter with a +3.00 add (95% CI -1.65 to 1.56, P = .95). The mean change in vertical deviation was 0.18 prism diopters at 6 meters (95% CI -0.19 to 0.56, P = .34), 0.57 prism diopters at 1/3 meter (95% CI 0-1.15, P = .05), and 0.47 prism diopters at 1/3 meter with a +3.00 add (95% CI -0.23 to 1.17, P = .18).

conclusionsPupil dilation does not meaningfully affect vertical or horizontal strabismus measurements in adults. Mild variability at near in younger patients is eliminated with the use of a +3.00 add.
