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

Four new complementation groups of mutations which confer resistance to several amino acid analogs in Saccharomyces cerevisiae are described. These mutants were isolated on medium containing urea as the nitrogen source, in contrast to previous studies that had used medium containing proline. All four resistance to amino acid analog (raa) complementation groups appear to confer resistance by reducing amino acid analog and amino acid uptake. In some genetic backgrounds, raa leu2 and raa thr4 double mutants are inviable, even on rich medium. The raa4 mutation may affect multiple amino acid transport systems, since raa4 mutants are unable to use proline as a nitrogen source. raa4 is, however, unlinked to a previously described amino acid analog resistance and proline uptake mutant, aap1, or to the general amino acid permease mutant gap1. Both raa4 and gap1 prevent uptake of [3H]leucine in liquid cultures. The raa1, raa2, and raa3 mutants affect only a subset of the amino acid analogs and amino acids affected by raa4. The phenotypes of raa1, -2, and -3 mutants are readily observed on agar plates but are not seen in uptake and incorporation of amino acids measured in liquid media.
