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

Dyes in industrial effluents constitute a major source of environmental pollution, posing a threat to human life. The use of enzymes for bioremediation is a greener, more efficient approach than conventional methods. This study reported partial purification of a novel peroxidase (POD) from Carica papaya (pawpaw) peels using a two-step approach: 80% ammonium sulfate precipitation followed by gel filtration chromatography on Sephadex G-200. The enzyme was purified up to 24-fold with 23% yield and a specific activity of 6020.9 U/mg proteins. The molecular weight of the enzyme, determined by gel filtration, was 54.82 kDa, and the pH and temperature optima were 5.5 and 40 °C, respectively. The apparent Michaelis-Menten constants (K
