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

Corticosteroids, such as dexamethasone, are clinically used in intravitreal injections for the treatment of inflammatory and age-related ocular diseases; however, frequent injections can cause complications. To prolong the retention of dexamethasone in the eye after intravitreal administration, sustained-release drug delivery systems have previously been investigated. The aim of this study was to evaluate the in vivo release of dexamethasone from a self-healing thermosensitive hydrogel consisting of a thermosensitive ABA triblock copolymer and to investigate its safety after its injection into the eyes of rats and rabbits. The polymer building block for hydrogel preparation was synthesized by copolymerization of a methacrylated dexamethasone prodrug (mDEX) with
