Rat liver nucleotide pyrophosphatase/phosphodiesterase is an efficient adenylyl transferase.

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
Rat liver nucleotide pyrophosphatase/phosphodiesterase I (NPP/PDE) catalysed efficiently the transfer of adenylate from ATP to alcohols (methanol, ethanol, propanol, ethylene glycol, glycerol, 2, 2-dichloroethanol and glycerol 2-phosphate), which acted as adenylate acceptors competing with water with different efficiencies. NPP/PDE kinetics in alcohol/water mixtures were accounted for by rate equations for competitive substrates, modified to include alcohol negative co-operativity and, depending on the nature of the alcohol, enzyme denaturation by high alcohol concentrations or activation by low alcohol concentrations. The correlation of alcohol efficiencies with alcohol acidities, the comparison of rat liver with snake venom NPP/PDE, and the different effects of ionic additives on the efficiencies of glycerol 2-phosphate and glycerol provided evidence for interaction of the alcohols with a base catalyst, a non-polar and a cationic subsite in the active centre of rat liver NPP/PDE. The enzyme thus appears to be well suited to act as transferase, and we propose that NPP/PDE could be an adenylylating agent in the membrane.
