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

Thirteen-lined ground squirrels (Ictidomys tridecemlineatus Mitchill 1821; 13-LGS) are useful diurnal rodent models of human cone-mediated vision due to their cone photoreceptor-dominant retinas. To develop the 13-LGS as a better model of inherited human visual disorders, we report a gene-editing protocol targeting the 13-LGS tyrosinase (Tyr) gene. CRISPR/Cas9 microinjection into donor embryos, followed by transfer to pseudo-pregnant recipients, yielded two Tyr-mutated founders. Mating these two to wild-type 13-LGS resulted in 22 offspring, of which five were genotyped with either a 17-bp deletion, 1-bp insertion, or 7-bp deletion Tyr mutation. These results demonstrated that this valuable mammalian model is amenable to germline gene editing by conventional methods.
