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

Direct ethanol fuel cells (DEFCs) are promising clean energy devices, but their efficiency is limited by the low C-C bond cleavage efficiency of Pd-based catalysts. Herein, we synthesized In-Mo codoped Pd metallene with rich interface defects via a simple wet-chemical method, which consists of face-centered cubic, intermetallic and amorphous phases. The catalyst's structure and ethanol electrooxidation reaction (EOR) performance was systematically characterized, and the mechanism was revealed by in situ ATR-FTIR, HPLC and DFT calculations. Results showed that the optimal PdInMo metallene exhibited a C1 pathway selectivity of 73.68%, which was 12.02 time that of commercial Pd/C. Its mass activity and specific activity were 4273.8 mA mg
