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.
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
A novel nodule-specific gene, LjNOD70, associated with late stages in Lotus japonicus nodule development and/or functioning was characterized. The LjNOD70 gene is a member of a small family of closely related L. japonicus genes. Two major mRNA species corresponding to the LjNOD70 gene were identified in nodules and shown to be the result of a mechanism resembling alternative splicing. The longer, presumably unspliced, mRNA species was shown to contain a single open reading frame (ORF), encoding a polytopic hydrophobic protein, LjN70, with a predicted molecular mass of 70 kDa. The second, presumably spliced, mRNA species was shown to be less abundant in nodules. The absence of the presumptive 'intron' was found to divide the reading frame into an upstream and a downstream ORF encoding the partial N- and C-terminal regions of the LjN70 protein, respectively. The predicted amino acid sequence of nodulin LjN70 revealed structural features characteristic of transport proteins, and was found to share similarity with the oxalate/formate exchange protein of Oxalobacter formigenes. Therefore, we postulate that the L. japonicus LjNOD70 gene family encodes nodule-specific transport proteins, which may have evolved as a result of exon-intron shuffling.
