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

aimTo report the clinical features and evolution of zone II retinopathy of prematurity (ROP).

methodsRetCam images of preterm infants with zone II ROP at our hospital between January 2009 and January 2019 were reviewed. The location, extent, and severity of ROP were recorded. Eyes were classified as type 1 zone II, type 2 zone II, and mild zone II ROP. The clinical features and evolution of zone II ROP were analyzed.

resultsIn total, 184 infants (302 eyes) were enrolled. Of these, 55 eyes (18%) developed type 1 zone II ROP, 39 eyes (13%) developed type 2 zone II ROP, and 208 eyes (69%) developed mild zone II ROP. The proportion of type 1 zone II ROP significantly decreased over the 10y. The onset of type 2 zone II and mild zone II ROP were 1wk earlier than type 1 zone II, and both regressed at 45wk. Isolated neovascular tuft (popcorn) and double track signs were characteristic manifestations of zone II ROP. Eighty-seven percent of type 1 zone II ROP regressed completely with an unfavorable outcome that emerged in seven eyes after laser treatment.

conclusionZone II is an area with ROP disease at various risk levels. Zone II ROP has unique clinical presentations like popcorn and double track signs. Over time, the proportion of zone II ROP with high risk gradually decrease and respond well to therapy.
