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
Soil fertility decline and overuse of agrochemicals threaten sustainable maize (Zea mays L.) production in semi-arid regions of Türkiye. Plant growth-promoting bacteria (PGPB) offer a biologically based alternative by enhancing nutrient uptake, root development, and soil health. In this field-based study, we evaluated the effects of a five-strain PGPR consortium (Azotobacter spp., Bacillus sp., Paenibacillus sp., Pantoea sp., and Pseudomonas sp.) on maize productivity and soil nutrient dynamics. A randomized split-plot design was used, involving four commercial maize hybrids and four inoculant doses (0, 100, 130, 160 mL/da). PGPR application significantly improved soil organic matter, phosphorus availability, and cation exchange capacity, particularly at the tasseling stage. The 130 mL/da dose yielded the highest grain productivity, suggesting optimized biological nitrogen fixation and water-use efficiency. Leaf analysis at the V15 stage revealed genotype-specific nutrient responses and elevated Zn and Cu levels under inoculated treatments, indicating enhanced micronutrient solubilization but also potential risk of nutrient imbalance. Our findings support the use of non-commercial, field-formulated PGPR consortia as a scalable component of sustainable maize systems, especially under climate-stressed conditions. The cultivar × dose interaction underscores the need for genotype-specific microbial strategies in precision agriculture.
