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

Some species of legumes and nine other flowering plant families form symbioses with bacteria that fix atmospheric nitrogen within specialized plant structures called nodules. How and how often nodulation symbiosis originated has implications for engineering symbiotic nitrogen fixation in non-legume crops. The prevailing hypothesis of a single origin with massive parallel losses has been challenged in a phylogenomic study favoring 16 origins and 10 losses. Nodulation has been assembled once or many times from existing processes (e.g., mycorrhizal symbiosis) and therefore almost nothing about it is truly novel. Because any feature of nodulation can be explained either as divergence from a common origin or as convergence in unrelated taxa, tests are needed that can distinguish whether assembly of homologous components has occurred uniquely or convergently. Much needs to be learned about nodulation symbioses across the proposed independent origins, especially involving the master nodulation transcription factor, Nodule Inception (NIN).
