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

Tetracycline (TC) and Cr(VI) often co-occur in wastewaters, where their synergistic toxicity and contrasting redox behaviors complicate remediation. In this study, ultrasonic cavitation was employed as a employed as a green and efficient process to simultaneously degrade TC and reduce Cr(VI). Under optimal conditions (20 kHz, 12 mm probe, 131 μm amplitude, 308 K), TC and Cr(VI) removal reached 62.9 % and 70.8 % within 2 h, respectively. The synergistic mechanism was elucidated through radical quenching, electron paramagnetic resonance (EPR) spectroscopy, and complementary computational fluid dynamics (CFD) simulations and density functional theory (DFT) calculations. Cavitation bubble collapse generated both oxidative and reductive radicals, enabling concurrent oxidation and reduction. Radical identification showed that ·O
