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
purposeRhizosheath is an adaptive feature for the survival of Stipagrostis pennata in desert systems. Although microorganisms play important ecological roles in promoting the nitrogen cycle of rhizosheath, the diversity and function of nitrogen-fixing microorganism communities have not been fully understood. MATERIALS AND
methodsTherefore, the aim of the present study is to explore the nitrogen fixation ability of rhizosheaths and the changes in abundance of nitrogen-fixing microorganisms at different growth periods of S. pennata. We sequenced the nifH gene through sequencing to identify the structure and diversity of nitrogen-fixing microorganisms of S. pennata at different growth periods of rhizosheaths.
resultsA total of 1256 operational taxonomic units (OTUs) were identified by nifH sequence and distributed in different growth periods. There were five OTUs distributed in each sample at the same time, and the abundance and diversity of microorganisms in fruit period were much higher than those in other periods. Mainly four phyla were involved, among which Proteobacteria was the most abundant in all groups.
conclusionsIn general, the present study investigated the abundance and characteristics of nitrogen-fixing microorganisms of rhizosheaths in different growth periods of S. pennata. It also may elucidate and indicate that the structure of nitrogen-fixing microorganisms of rhizosheaths in different growth periods of S. pennata had changed.
