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 multicellular developmental cycle of Myxococcus xanthus requires large-scale changes in gene transcription, and recent findings indicate that NtrC-like activators play a prominent role in regulating these changes. In this study, we made insertions in 28 uncharacterized ntrC-like activator (nla) genes and found that eight of these insertions cause developmental defects. Hence, these results are consistent with the idea that M. xanthus uses a series of different NtrC-like activators during fruiting body development. Four of the eight developmental mutants we identified have motility defects. The nla1, nla19, and nla23 mutants show S-motility defects, while the nla24 mutant shows defects in both S-motility and A-motility. During development, aggregation of the nla1, nla19, and nla23 mutants is delayed slightly and the nla24 mutant shows no signs of aggregation or sporulation. The nla4, nla6, nla18, and nla28 mutants have no appreciable loss in motility, but they fail to aggregate and to sporulate normally. The nla18 mutant belongs to a special class of developmental mutants whose defects can be rescued when they are codeveloped with wild-type cells, suggesting that nla18 fails to produce a cell-cell signal required for development. The three remaining activator mutants, nla4, nla6, and nla28, appear to have complex developmental phenotypes that include deficiencies in cell-cell developmental signals.
