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

A ncl-1 mutation results in enlarged nucleoli, which can be detected in nearly all cells of living animals by Nomarski microscopy. Spontaneous mitotic loss of a ncl-1(+)-containing free duplication in an otherwise homozygous ncl-1 mutant animal results in mosaicism for ncl-1 expression, and the patterns of mosaicism lead us to conclude that ncl-1 acts cell autonomously. The probability of mitotic loss of the duplication sDp3 is approximately constant over many cell divisions. About 60% of the losses of sDp3 at the first embryonic cell division involve nondisjunction. Frequencies of mitotic loss of different ncl-1(+)-bearing free duplications varied over a 200-fold range. The frequencies of mitotic loss were enhanced by a chromosomal him-10 mutation. We have used ncl-1 as a cell autonomous marker in the mosaic analysis of dpy-1 and lin-37. The focus of action of dpy-1 is in hypodermis. A mutation in lin-37 combined with a mutation in another gene results in a synthetic multivulva phenotype. We show that lin-37 acts cell nonautonomously and propose that it plays a role, along with the previously studied gene lin-15, in the generation of an intercellular signal by hyp7 that represses vulval development.
