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.
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
In this study, the effects of operating temperature on pore-scale gas bubble transport in a carbon-based anode porous transport layer (PTL) of a polymer electrolyte membrane (PEM) electrolyzer is revealed using operando X-ray computed tomography (CT). Higher temperature operation (80 °C compared to 40 °C) led to a lower total gas bubble volume fraction in the PTL (0.25 to 0.17; 32% lower), which is attributed to improved water transport and gas removal. Higher temperatures led to fewer bubbles in the PTL (13% less at 80 °C compared to 40 °C) as well as a greater occurrence of smaller bubbles (35% increase in skewness of the bubble size distribution), and this behavior is attributed to faster rates of nucleation and bubble detachment from the electrode. The formation of gas slugs is also observed in the anode channels at 60 °C and 80 °C, which is attributed to the faster detachment and coalescence of bubbles from the PTL/flow field interface.
