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
Thioredoxins (TRXs) are small ubiquitous oxidoreductases involved in disulfide bond reduction of a large panel of target proteins. The most complex cluster in the family of plant TRXs is formed by h-type TRXs. In Arabidopsis (Arabidopsis thaliana), nine members of this subgroup were described, which are less well known than their plastidial counterparts. The functional study of type-h TRXs is difficult because of the high number of isoforms and their similar biochemical characteristics, thus raising the question whether they have specific or redundant functions. Type-h TRXs are involved in seed germination and self incompatibility in pollen-pistil interaction. Their function as antioxidants has recently been proposed, but further work is needed to clarify this function in plants. In this study, we describe two new h-type TRXs from pea (Pisum sativum; stated PsTRXh1 and PsTRXh2). By functional complementation of a yeast (Saccharomyces cerevisiae) trx1Delta trx2Delta double mutant, we demonstrate that PsTRXh1 is involved in the redox-imbalance control, possibly through its interaction with peroxiredoxins. In contrast, PsTRXh2 provokes a phenotype of hypersensitivity to hydrogen peroxide in the yeast mutant. Furthermore, we show differential gene expression and protein accumulation of the two isoforms, PsTRXh1 protein being abundantly detected in vascular tissue and flowers, whereas PsTRXh2 gene expression was hardly detectable. By comparison with previous data of additional PsTRXh isoforms, our results indicate specific functions for the pea h-type TRXs so far described.
