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

purposeThe purpose of this study was to determine the incidence, severity, and associated risk factors of retinopathy of prematurity (ROP) in a district in South India.

methodsThis was a prospective, observational, cohort study involving babies at risk of ROP conducted in five Neonatal Intensive Care Units in a district in Tamil Nadu, South India. All babies with gestational age at birth of ≤36 weeks and a birth weight (BW) of ≤1900 g with a follow-up period of at least 6 months were enrolled for the study. Neonatal and maternal risk factors were assessed and univariate and multivariate logistic regression analysis performed to examine the predictors of ROP.

resultsA total of 325 infants were screened. ROP was identified in 210 eyes of 106 (32.6%) babies with severe ROP (stage ≥3 ROP) occurring in 14 (13.2%) babies. Low BW (LBW) was the only significant risk factor for ROP on multivariate logistic regression analysis. The mean BW was 1285 and 1452 g for babies with and without ROP, respectively. Treatment was indicated in 22 eyes of 14 (13.2%) infants.

conclusionsThe incidence of ROP was fairly high and strongly associated with LBW. A relatively low incidence of severe ROP was, however, observed. More effort is, therefore, required towards the prevention of preterm births while the present gains in neonatal care should be sustained to reduce the incidence of ROP and thus childhood blindness in the country.
