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

purposeMacular development is a complex process that starts by mid-gestation and continues several years after birth. A preterm birth could affect this development, causing increased thickness in the central macula, but the effect of the macular function remains uncertain. The aim of this study was to investigate the macular function measured with multifocal electroretinography (mfERG), in former preterm children and compare with healthy controls. A second aim was to correlate central macular function with central macular thickness measured with optical coherent tomography (OCT), in the preterm group.

methodsFifteen former preterm children born before 32 weeks of gestation were included in the study. MfERG results from 12 children acted as controls. Visual acuity, refraction in cycloplegia and mfERG were carried out in all children, and optical coherent tomography (OCT) was performed in the preterm children. Main outcomes were P1 amplitudes and implicit times for Rings 1-5 and "sum of groups" of the mfERG, and central macula thickness in area A1 measured with OCT.

resultsThe P1 amplitudes were reduced in Rings 1-5 and "Sum of groups" in the preterm children compared to controls. There were no significant correlation between P1 amplitude or implicit times in Ring 1 and central macular thickness in the preterm group.

conclusionsMacular function is reduced in former preterm children compared to children born at term. This suggests that the structural changes with a thicker central retina can have an effect on function and may be one, of probably several, explanations for visual dysfunction in preterm children at school age.
