Phosphate Mobilization by Culturable Fungi and Their Capacity to Increase Soil P Availability and Promote Barley Growth.
Article in Current microbiology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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
Large-scale screening of 848 culturable soil and endophytic filamentous fungi and yeasts for the ability to mobilize inorganic and organic P compounds was performed. Five strains of filamentous fungi having the highest level of phosphate-mobilizing ability were selected: Penicillium bilaiae Pb14, P. bilaiae C11, P. rubens EF5, Talaromyces pinophilus T14, and Aspergillus sp. D1. These strains in vitro actively solubilized Ca, Al, and Fe phosphates and Ca phytate. The amount of mobilized P negatively correlated with pH of the medium and positively correlated with fungal biomass. The proposed mechanisms for P mobilization were acidification of the medium, organic acid release, and phosphatase activity. The fungi decreased pH of the medium from 7.0 to 2.3-5.0. Ten different organic acids were produced by fungi with pyruvic acid being a major component. Acid phosphatase activity varied from 0.12 EU to 0.84 EU, and alkaline phosphatase activity varied from 0.08 EU to 0.61 EU depending on the strain. Available P concentration in soil was increased by 13-28% after introduction of the fungi. The fungi also produced phytohormones auxins, salicylic acid, and abscisic acid. All the strains, except Aspergillus sp. D1, promoted elongation and increased biomass of barley seedlings grown in soil. Shoot P concentration increased by 17-26% after inoculation with P. bilaiae Pb14, T. pinophilus T14, and Aspergillus sp. D1. It was concluded that the selected fungal strains promoted plant growth due to P mobilization and phytohormone production.
