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

This study investigates the wavelength-dependent reactivity of the three germanium-based type I photoinitiators bis(4-methoxybenzoyl)diethylgermane (Ivocerin®), tris(2,4,6-trimethylbenzoyl)ethylgermane, and tetrakis(2-methylbenzoyl)germane. By systematically varying LED wavelengths from 365 to 495 nm, we quantify quantum efficiencies/absorbance and correlate them with the photobleaching behavior and penetration depths. The results highlight the crucial relationship between the emission profile of the light source and the efficiency of the photoinitiators. These insights are particularly relevant for optimizing light-driven processes in applications such as biomedical printing, adhesives, and spatially controlled polymerization.
