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
MAIN
conclusionHalotolerant rhizospheric bacteria Providencia rettgeri ST202 positively modulated the changes in stomatal, mesophyll, and biochemical limitations, fine-tuning photosynthesis, photorespiration, ROS, and antioxidants in rice and tomato plants for improved salinity tolerance. Soil salinity is detrimental for survival of majority of crops, since increased salt disrupts root water uptake, induces cellular ion toxicity ultimately leading to drastic decrease in crop yields. In the current study, inoculation of Providencia rettgeri ST202, a halotolerant rhizospheric bacteria isolated from rhizospheric soil of salt pan areas, resulted in plant growth-promoting traits along with improvement in growth of Oryza sativa and Lycopersicon esculentum plants under normal and salinity stress (S2: 200 mM and S4: 400 mM NaCl) conditions prompting us to evaluate changes in physiological and biochemical parameters, photosynthesis, photorespiration, reactive oxygen species (ROS), and antioxidants. Compared to uninoculated plants, improved relative water content, chlorophyll content, carotenoids, and antioxidant levels were observed along with decreased electrolyte leakage and ROS in ST202 inoculated rice and tomato plants suggesting better protection under control and salinity stress. While salinity stress severely impacted photosynthesis under different light intensities and different CO
