Sonocatalytic degradation of RB-5 dye using ZnO nanoparticles doped with transition metals.

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, ZnO was doped and co-doped with rhodium and tungsten to assess the impact of these transition metals on the sonocatalytic degradation of reactive black 5 azo dye (RB-5). Structural analysis revealed that doping ZnO with 1% Rh and W does not alter its wurtzite hexagonal structure, although minor changes in cell parameters were observed due to differences in electronic density. Interestingly, co-doping resulted in lower degradation efficiency than single doping, with W-ZnO emerging as the most effective catalyst, achieving 100% RB-5 degradation within 60 min, likely due to a higher density of oxygen vacancies and hydroxyl groups. Moreover, a 2
