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 development of metal-free electrocatalysts for the oxygen reduction reaction (ORR) is crucial for next-generation energy technologies, offering cost reduction, improved stability, and independence from scarce noble metals. Covalent organic frameworks (COFs) have emerged as promising candidates due to their tunable porosity, high surface area, and structural versatility. In this study, we report a hydroxyl-functionalized enamine- and imine-linked two-dimensional (2D) COFs (TFPh_DHPh_COF) as an efficient ORR electrocatalyst in alkaline media. The enamine (─C─NH─) linkages enhance structural integrity through hydrogen-bonding interaction, whereas imine (─C═N─) linkages contribute to electron density modulation, stabilizing key intermediates and facilitating a favorable four-electron ORR pathway. Natural bond orbital (NBO) analysis from computational study, reveals a partial positive charge (C
