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

Toluene electrooxidation offers a sustainable route for the synthesis of valuable oxygen-containing chemicals, but existing methods often rely on strongly acidic or basic electrolytes, high cell voltages, or soluble mediators that complicate catalyst separation and increase waste. In this study, we show that combining grafted 2,2,6,6-tetramethylpiperidine N-oxyl (TEMPO) units with atomically dispersed iron sites in nitrogen-doped carbon enables efficient and selective electrooxidation of toluene to benzaldehyde under mild conditions. The catalyst operates at low potentials of 1.5 ~ 1.8 V vs. Ag/Ag
