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
Photocatalytic degradation of perfluorooctanoic acid (PFOA) has drawn great attention in the past. These studies have focused on developing high-efficacy photocatalysts and understanding the reaction mechanisms and structure-performance relationships. However, the photocatalytic degradation efficacy and kinetics under environmentally relevant conditions and the reduced toxicological impact of degraded PFAS products are lacking. To fill in this gap, we developed a photocatalytic system to deconstruct perfluorooctanoic acid (PFOA) under ambient conditions using sunlight as a renewable energy source. We evaluated the degradation pathway and reaction mechanisms using high-resolution mass spectrometry (LC/MS-MS) and product portfolio. The photocatalytic degradation of PFOA in environmental water matrices was set up over a two-week period using natural sunlight outdoors. The toxicity of degraded products was assessed in parallel using duckweed, or
