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

Enzymes from halophilic organisms function in near-saturating salt concentrations. To explore enzyme adaptation to these conditions and the broader effects of salt on enzyme catalysis, we examined the salt effect on the kinetics of a glucose-6-phosphate dehydrogenase from the halophilic archaeon Haloferax volcanii (HvG6PDH). This enzyme has a negatively charged surface and catalyzes the oxidation of the negatively charged substrate glucose-6-phosphate (G6PDH activity) and glucose (glcDH activity). We found strikingly different salt effects on the two activities. Steady-state kinetics experiments revealed a 50-fold decrease in K
