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
Auxin transport proteins may be involved in nodule development. As a prelude to investigating the roles of these proteins in nodule development, we took advantage of the genetic and molecular resources available in the legume Medicago truncatula to characterize the gene families encoding auxin efflux and influx carriers. We identified ten auxin efflux carrier sequences (MtPINs) and five auxin influx/permease sequences (MtLAXs). The genomic sequence of each of these fifteen genes was determined, the genes were mapped on the publicly available map of M. truncatula, and their expression was examined in shoot and root tissue of nodulating plants. With one exception, transcripts of all MtPIN genes were detected. The expression of MtPIN2 was limited to nodulating roots, while transcripts of all other expressed genes were detected in both shoots and roots. Both the PIN and LAX gene families contain more members in M. truncatula than in Arabidopsis, but the gene families are not significantly expanded. Sequence comparison of the M. truncatula PIN and LAX genes with PIN and LAX genes from other dicots and monocots indicates that both gene families share a common overall structure, with areas of high homology both within M. truncatula and across species boundaries. Molecular phylogenies of both the PIN and LAX gene families were constructed. Combined with intron position and expression data, the phylogenies were used to assign relationships between MtPIN and MtLAX genes and the orthologous Arabidopsis PIN and LAX genes. MtPIN2 and MtPIN7 appear to be the result of a recent gene duplication with subsequent divergence of expression patterns. These results set the stage for the use of these genes in research on the role of auxin in nodulation.
