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

Ether oxygen-based covalent organic frameworks (EO-COFs) with intrinsic flexibility characteristics hold promise for applications in emerging electrochemical energy conversion technologies due to the adaptable pore microenvironments. However, achieving efficient oxygen reduction reaction (ORR) requires not only accessible pores but also facilitated charge transfer from the electrode to catalytically active sites within the extended framework and the simultaneous optimization of these two coupled processes remains challenging. Here, we synthesized two new EO-COFs and incorporated electron-withdrawing triazine units to enhance charge-transfer capability and modulate the electronic states, thereby improving their metal-free ORR activity. Moreover, the ether-oxygen moieties contribute to the formation of a more adaptive pore microenvironment and facilitate mass transport. Notably, the optimized THD-TOT-COF exhibits a high half-wave potential of 0.77 V and a turnover frequency value of 0.0021 s
