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
key messageOur results indicate that OsPGK2a-P gene is differentially regulated in contrasting rice cultivars under stress and its overexpression confers salt stress tolerance in transgenic tobacco. Phosphoglycerate kinase (PGK; EC = 2.7.2.3) plays a major role for ATP production during glycolysis and 1, 3-bisphosphoglycerate production to participate in the Calvin cycle for carbon fixation in plants. Whole genome analysis of rice reveals the presence of four PGK genes (OsPgks) on different chromosomes. Comparative expression analysis of OsPgks in rice revealed highest level of transcripts for OsPgk2 at most of its developmental stages. Detailed characterization of OsPgk2 transcript and protein showed that it is strongly induced by salinity stress in two contrasting genotypes of rice, i.e., cv IR64 (salt sensitive) and landrace Pokkali (salt tolerant). Ectopic expression of OsPgk2a-P (isolated from Pokkali) in transgenic tobacco improved its salinity stress tolerance by higher chlorophyll retention and enhanced proline accumulation, besides maintaining better ion homeostasis. Ectopically expressing OsPgk2a-P transgenic tobacco plants showed tall phenotype with more number of pods than wild-type plants. Therefore, OsPgk2a-P appears to be a potential candidate for increasing salinity stress tolerance and enhanced yield in crop plants.
