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

The size and organization of the brain neocortex has dramatically changed during primate evolution. This is probably due to the emergence of novel genes after duplication events, evolutionary changes in gene expression, and/or acceleration in protein evolution. Here, we describe a human Ret finger protein-like (hRFPL)1,2,3 gene cluster on chromosome 22, which is transactivated by the corticogenic transcription factor Pax6. High hRFPL1,2,3 transcript levels were detected at the onset of neurogenesis in differentiating human embryonic stem cells and in the developing human neocortex, whereas the unique murine RFPL gene is expressed in liver but not in neural tissue. Study of the evolutionary history of the RFPL gene family revealed that the RFPL1,2,3 gene ancestor emerged after the Euarchonta-Glires split. Subsequent duplication events led to the presence of multiple RFPL1,2,3 genes in Catarrhini ( approximately 34 mya) resulting in an increase in gene copy number in the hominoid lineage. In Catarrhini, RFPL1,2,3 expression profile diverged toward the neocortex and cerebellum over the liver. Importantly, humans showed a striking increase in cortical RFPL1,2,3 expression in comparison to their cerebellum, and to chimpanzee and macaque neocortex. Acceleration in RFPL-protein evolution was also observed with signs of positive selection in the RFPL1,2,3 cluster and two neofunctionalization events (acquisition of a specific RFPL-Defining Motif in all RFPLs and of a N-terminal 29 amino-acid sequence in catarrhinian RFPL1,2,3). Thus, we propose that the recent emergence and multiplication of the RFPL1,2,3 genes contribute to changes in primate neocortex size and/or organization.
