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.
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
Photolabile hydrogels have gained tremendous interest for a wide range of applications in materials and life sciences. Usually, photodegradability is introduced via chromophores and labile bonds, making such materials intrinsically light sensitive. In recent years, disulfide bonds have emerged as an innovative alternative, as they can be selectively cleaved in the presence of (photo)generated radicals. However, such materials suffer from limited network stability and high swelling as a result of thiol-disulfide metathesis reactions. Herein, we present two strategies to counteract such phenomena by network stabilization either via physical or chemical incorporation of (un)modified gelatin macromers to norbornene-modified poly(vinyl alcohol) networks. Photolabile behavior was introduced by a simple disulfide-containing dithiol cross-linker. Tunable material properties were investigated by means of in situ photorheology, in vitro swelling, and degradation experiments. Finally, we demonstrate an innovative method for localized disulfide cleavage via two-photon micropatterning.
