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

Studies of cold-active enzymes may elucidate the basis for low-temperature activity and contribute to their wider application in energy-efficient processes. Here we investigate the cold-active GH2 β-galactosidase from the psychrophilic bacterium Alkalilactibacillus ikkensis (AiLac). AiLac has a specific activity twice as high as its closest structural homolog (the mesophilic Escherichia coli GH2 β-galactosidase) toward the lactose analog ONPG at room temperature and neutral pH, and shows biphasic behavior in Michaelis-Menten plots. AiLac is activated by Mg
