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 near-infrared (NIR) sensitized generation of lophyl radicals (L·) by heptamethine cyanine led to initiation of radical photopolymerization of multifunctional acrylates when different hexa-arylbisimidazoles (HABIs) and N-phenylglycine (NPG) operated as coinitiator. The latter functioned as donor. For a deeper understanding, heptamethine cyanines were used following a photoinduced electron transfer (PET). HABI derivatives with electron-donating and -withdrawing substituents demonstrated that those with electron acceptors resulted in a higher photopolymerization efficiency of multifunctional acrylates. Tri-(propylene glycol) diacrylate (TPGDA) and tri-methylolpropane triacrylate (TMPTA) served as the monomers. Sensitizers (Sens) exposed with a high intense NIR-light source at 808 nm exhibiting a positive charge in the cyanine pattern significantly operate more efficiently for radical photopolymerization than a Sens without a positive charge. Differences in efficiency of PET can give an explanation for these differences. The heat generated by the cyanine's internal conversion from S
