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 energy conversion efficiency of solid oxide fuel cells is primarily governed by the performance of their air electrodes. Several surface modification techniques, including nanocatalyst decoration, surface coating, and acid etching, have been reported to enhance the performance of air electrodes. However, these approaches often face limitations in cost and time efficiency. In this study, we propose alkaline leaching as a straightforward and innovative strategy to activate the surface of mixed-conducting oxides by selectively dissolving the A-site cation during bias application in an alkaline solution. After 10 min of alkaline leaching, the surface of the PrBa
