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

Encoding a conserved protein of unknown function, the Medicago truncatula RDN1 gene is involved in autoregulation of nodulation through signaling in the root.  In contrast, the SUNN kinase in M. truncatula has been shown by grafting of mutant scions to control nodule number in the root by communication of a signal from the shoot to the root.  GUS staining patterns resulting from expression of the SUNN promoter fused to uidA showed expression of SUNN in most parts of plant including the root, but confined to the vascular tissue, a pattern that overlaps with that published for RDN1.  Real Time qRT-PCR analysis showed levels of both SUNN RNA and RDN1 RNA did not change significantly during early nodulation signaling (0-72 hours after inoculation).  The similarity in expression in cell types strongly suggests vascular signaling for nodule number regulation, while the lack of changes over early nodule development suggest post transcriptional mechanisms such as protein association or phosphorylation transmit the signal.
