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
Peptide deformylase can catalyse the removal of formyl groups from the N-terminal formyl methionine of the primary polypeptide chain. The peptide deformylase genes of a few herbaceous plants have been studied to some extent, but the peptide deformylase genes of woody plants have not been studied. In this study, we isolated EuPDF1B from Eucommia ulmoides Oliv. The full-length sequence of EuPDF1B is 1176 bp long with a poly-A tail and contains an open reading frame of 831 bp that encodes a protein of 276 amino acids. EuPDF1B was localized to the chloroplast. qRT‒PCR analysis revealed that this gene was expressed in almost all tissues tested but mainly in mature leaves. Moreover, the expression of EuPDF1B was enhanced by ABA, MeJA and GA and inhibited by shading treatment. The expression pattern of EuPDF1B was further confirmed in EuPDF1Bp: GUS transgenic tobacco plants. Among all the transgenic tobacco plants, EuPDF1Bp-3 showed the highest GUS histochemical staining and activity in different tissues. This difference may be related to the presence of enhancer elements in the region from - 891 bp to - 236 bp of the EuPDF1B promoter. In addition, the expression of the chloroplast gene psbA and the net photosynthetic rate, fresh weight and height of tobacco plants overexpressing EuPDF1B were greater than those of the wild-type tobacco plants, suggesting that EuPDF1B may promote the growth of transgenic tobacco plants. This is the first time that PDF and its promoter have been cloned from woody plants, laying a foundation for further analysis of the function of PDF and the regulation of its expression.
