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 protocol describes a step-by-step approach for the synthesis of a periodic mesoporous organosilica (PMO) with wall-embedded nitroxide monoradicals. It starts with the synthesis of an isoindoline-based nitroxide monoradical and its silylationa critical requirement for the condensation with the PMO's bisilylated building block. We also provide detailed instructions on how to synthesize the phenylene (Ph)-PMO's bisilylated precursor, 1,4-bis-(triethoxysilyl)-benzene (BTEB), and subsequent preparation of the Ph-PMO with in situ incorporation of the silylated nitroxide monoradical. The incorporation of the nitroxide into the Ph-PMO was monitored by electron paramagnetic resonance (EPR) spectroscopy, which clearly revealed the decrease in free radical concentration in solution as the condensation progressed. A comparison of the radical-containing Ph-PMO to a reference Ph-PMO, prepared from the same organic precursor in the absence of the radical, by powder X-ray diffraction (PXRD), N
