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

The topical administration of in situ hydrogels for ocular pathologies is a promising application strategy for providing high effectiveness and patient compliance. Curcumin, a natural polyphenol, possesses all the prerequisites for successful therapy of ophthalmic diseases, but unfortunately its physicochemical properties hurdle the practical use. Applying a composite in situ thermoresponsive hydrogel formulation embedded with polymer nanoparticles is a potent strategy to overcome all the identified drawbacks. In the present work we prepared uniform spherical nanoparticles (296.4 ± 3.1 nm) efficiently loaded with curcumin (EE% 82.5 ± 2.3%) based on the biocompatible and biodegradable poly-(lactic-co-glycolic acid). They were thoroughly physicochemically characterized in terms of FTIR, SEM, TGA, and DLS, in vitro release following Fickian diffusion (45.62 ± 2.37%), and stability over 6 months. Their lack of cytotoxicity was demonstrated in vitro on HaCaT cell lines, and the potential for antioxidant protection was also outlined, starting from concentrations as low as 0.1 µM and reaching 41% protection at 5 µM. An in situ thermoresponsive hydrogel (17%
