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 exact phylogenetic position of Gnetales, a small, highly modified group of gymnosperms with an accelerated rate of molecular evolution, is one of the most challenging issues for seed plant systematics. Recent results from entire plastid genome (ptDNA) sequencing revealed the absence of the entire suite of plastid ndh genes in several species of Gnetales and the pine family (Pinaceae) potentially highlighting a major structural feature linking these two groups-concerted loss of all plastid genes for the NADH dehydrogenase complex. However, the precise extent of ndh gene loss in gymnosperms has not been surveyed. Using a slot-blot hybridization method, we probed all 11 ndh genes in 162 species from 70 of 85 gymnosperm genera. We find that all ndh genes are absent across Gnetales and Pinaceae, but not in any other group of gymnosperms. This feature represents either a major synapomorphy for a clade consisting of these two lineages or, less likely, a convergent loss. Our survey substantially extends previous inferences based on more limited sampling and, if the former evolutionary interpretation is correct, it provides additional support for the contentious "gnepine" hypothesis, which places Gnetales as sister to Pinaceae.
