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

aimThis study evaluated the correlation between retinopathy of prematurity (ROP), anaemia and blood transfusions in extremely preterm infants.

methodsWe included 227 infants born below 28 weeks of gestation at King Edward Memorial Hospital, Perth, Australia, from 2014-2016. Birth characteristics and risk factors for ROP were retrieved, and anaemia and severe anaemia were defined as a haemoglobins of <110 g/L and <80 g/L, respectively. Logistic regression was used for the analysis.

resultsRetinopathy of prematurity treatment was needed in 11% of cases and the mean number of blood transfusions (p < 0.01), and mean number of weeks of anaemia (p < 0.001) and of severe anaemia (p < 0.05), had positive associations with ROP cases warranting treatment. In the multivariate logistic regression analysis, the best-fit model of risk factors included anaemic days during first week of life, with an odds ratio (OR) of 1.46% and 95% confidence interval (CI) of 1.16-1.83 (p < 0.05), sepsis during the first 4 weeks of life (OR 3.14, 95% CI 1.10-9.00, p < 0.05) and days of ventilation (OR 1.03, 95% CI 1.01-1.06, p < 0.05).

conclusionThe duration of anaemia during the first week of life was an independent risk factor for ROP warranting treatment and preventing early anaemia may decrease this risk.
