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

backgroundThe purpose of this study was to evaluate the refraction of eyes treated with diode laser photocoagulation for prethreshold retinopathy of prematurity (ROP) at a mean of 5 years after treatment. MATERIALS AND

methodsFifty infants with prethreshold ROP treated with diode laser at Hanoi Childrens' Hospital during the period 2008 to 2009 were reviewed. Refractive error was identified by cycloplegic refraction with Cyclogyl 1%. Myopia was divided into two categories based on magnitude: high myopia (more than -5.00 D) and low myopia (between 0 and -5.00 D). Hypermetropia was subdivided into low hypermetropia (between 0 and +5.00 D) and high hypermetropia (greater than +5.00 D). Astigmatism was classified as high if >2.00 D. Eyes with media opacification that interferes with retinoscopy were excluded. The refractive outcome was correlated with birth weight and gestational age. The anatomical and visual outcomes were recorded.

resultsOne hundred eyes from 50 infants were included in the study. The mean birth weight was 1,426.4 g and the mean gestational age was 29.88 weeks. After 5 years of follow-up, the average spherical equivalent for 100 eyes was -2.87 D. On cycloplegic retinoscopy, high myopia (more than -5.00 D) was seen in 32% of eyes. Twenty (20%) eyes had nonsignificant hypermetropia, and high hypermetropia (more +5.00 D) was seen in only one eye (1%). The prevalence of astigmatism and high astigmatism (more than -2.00 D) was 79% and 49%, respectively. Three infants (6%) had esotropia and two infants (4%) had exotropia. None of the infants had nystagmus.

conclusionThe majority of patients who underwent diode laser therapy for prethreshold ROP had favourable anatomical and visual outcomes. High refractive error is common and may be the cause of visual impairment.
