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
The pea late nodulin gene PsNOD6 has been cloned and sequenced. PsNOD6 is homologous to the pea early nodulin genes PsNOD3 and PsENOD14. In situ hybridization experiments showed that, like the PsENOD3 and PsENOD14 genes, the PsNOD6 gene is only expressed in the infected cell type. The PsNOD6 gene is first expressed at the transition of the pre-fixation zone II into the interzone II-III (the amyloplast-rich zone preceding the fixation zone III), whereas the early nodulin genes PsENOD3 and PsENOD14 are already induced in the pre-fixation zone II. Thus these nodulin genes encoding homologous proteins are induced at consecutive stages of nodule development. The expression of the late nodulin genes encoding leghaemoglobin precedes the expression of the late nodulin gene PsNOD6. Therefore these late nodulin genes have to be regulated by different mechanisms despite the fact they are expressed in the same cell type. This conclusion is consistent with the fact that PsNOD6 lacks one of the conserved regions occurring in the promoters of all other late nodulin genes studied.
