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
backgroundPentatricopeptide repeat (PPR) proteins are encoded by a large gene family of approximately 450 members in Arabidopsis and 477 in rice, which characterized by tandem repetitions of a degenerate 35 amino acid characteristic sequence motifs. A large majority of the PPR genes in the higher plants are localized in organelles. Their functions remain as yet largely unknown. The majority of characterized PPR proteins have been found to function in modulating the expression plastid and mitochondrial genes in plants.
resultsHere, a genome-wide identification and comparison of the PPR genes from 5 organisms was performed, including the moss Physcomitrella patens, the lycophyte Selaginella moellendorffii, the eudicot Arabidopsis, and the monocots rice and foxtail millet. It appears that the expansion of this gene family prior to the divergence of the euphyllophytes and the lycophytes in land plants. The duplication and divergence rates of the foxtail millet PPR genes (SiPPRs) showed that the expansion period of this gene family around 400 Mya, and indicated that genome segmental duplication was very likely the primary mechanism underlying the expansion of the PPR gene family in vascular plants. An analysis of a complete set of SiPPR genes/proteins that included classification, chromosomal location, orthologous relationships, duplication analysis, and auxiliary motifs is presented. Expression analysis of the SiPPR genes under stress conditions revealed that the expression of 24 SiPPR genes was responsive to abiotic stress. Subcellular localization analysis of 11 PPR proteins indicated that 5 proteins were localized to chloroplasts, that 4 were localized to mitochondria, and that 2 were localized to the cytoplasm.
conclusionsOur results contribute to a more comprehensive understanding the roles of PPR proteins and will be useful in the prioritization of particular PPR proteins for subsequent functional validation studies in foxtail millet.
