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

Olfactory receptor families have arisen independently several times during evolution. The origin of taar genes, one of the four major vertebrate olfactory receptor families, is disputed. We performed a phylogenetic analysis making use of 96 recently available genomes, and report that olfactory functionality has arisen twice independently within the TAAR family, once in jawed and once in jawless fish. In lamprey, an ancestral gene expanded to generate a large family of olfactory receptors, while the sister gene in jawed vertebrates did not expand and is not expressed in olfactory sensory neurons. Both clades do not exhibit the defining TAAR motif, and we suggest naming them taar-like receptors (tarl). We have identified the evolutionary origin of both taar and tarl genes in a duplication of the serotonergic receptor 4 that occurred in the most recent common ancestor of vertebrates. We infer two ancestral genes in bony fish (TAAR12, TAAR13) which gave rise to the complete repertoire of mammalian olfactory taar genes and to class II of the taar repertoire of teleost fish. We follow their evolution in seventy-one bony fish genomes and report a high evolutionary dynamic, with many late gene birth events and both early and late gene death events.
