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

BACKGROUND AND

aimsTribe Mirbelieae (Fabaceae) represents one of the great species radiations in Australian flora and the largest in the pea-flowered legumes. Traditional amplicon sequencing has failed to resolve relationships within this species-rich and morphologically diverse tribe.

methodsTarget-capture sequencing was used to reconstruct relationships within the core Mirbelioid legumes, which represent a previously hypothesized rapid radiation that dates to the Oligocene and early Miocene epochs. KEY

resultsWe recovered strongly supported deep nodes resolving relationships between all recognized genera and four novel clades based on 289 low-copy nuclear markers derived from the Angiosperms353 universal probe set. The taxonomically challenging genus Pultenaea was demonstrated to be polyphyletic. Minor changes are required in Aotus, Callistachys, Mirbelia, Oxylobium, Phyllota and Urodon.

conclusionsPhylogenomic data have robustly resolved relationships in a large legume clade where relationships were long feared irresolvable. This resolution enables the recognition of monophyletic genera within the tribe, with only minimal taxonomic rearrangements. Critically, a new circumscription of Pultenaea supported by both phylogenomic and morphological data has now been achieved.
