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

S-adenosylmethionine (AdoMet) synthetase (EC 2.5.1.6) is the enzyme that catalyzes the synthesis of AdoMet, a molecule important for all cellular organisms. We have cloned and characterized an AdoMet synthetase gene (sam1) from Pneumocystis spp. This gene was transcribed primarily as an approximately 1.3-kb mRNA which encodes a protein containing 381 amino acids in P. carinii or P. murina and 382 amino acids in P. jirovecii. sam1 was also transcribed as part of an apparent polycistronic transcript of approximately 5.6 kb, together with a putative chromatin remodeling protein homologous to Saccharomyces cerevisiae, CHD1. Recombinant Sam1, when expressed in Escherichia coli, showed functional enzyme activity. Immunoprecipitation and confocal immunofluorescence analysis using an antipeptide antibody showed that this enzyme is expressed in P. murina. Thus, Pneumocystis, like other organisms, can synthesize its own AdoMet and may not depend on its host for the supply of this important molecule.
