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
Bacteria that solubilize nutrients in the soil are commonly used as bio-inoculants for promoting the growth of different crop species. However, the influence of potassium (K) solubilizing bacteria (KSB) originating from saxicolous habitat (rock-dwelling) on plant growth has not been frequently examined. In this study, we isolated KSB from saxicolous habitats and estimated their ability to produce plant growth hormone, organic acids, and siderophore that may facilitate plant growth. Fifteen culturable saxicolous bacterial isolates with varied K solubilizing ability were isolated from two sites. Of these, four potential K solubilizers were selected and identified by 16S rRNA gene sequencing. The four bacterial isolates resembled Bacillus subtilis, Bacillus cereus, Bacillus licheniformis, and Burkholderia cenocepacia and produced different organic acids, indole acetic acid, and siderophore under in vitro conditions. Potassium solubilization differed among the bacterial isolates and was significantly influenced by K sources. Inoculation of KSB improved the tomato plant growth parameters like plant height, leaf area, total root length, root/shoot ratio, and tissue K content in sterilized and unsterilized Alfisol, and Vertisol soils under greenhouse conditions. We also observed higher residual K content in the KSB inoculated post-harvest soils. Among the four KSB isolates screened, B. licheniformis and B. cenocepacia presents an excellent prospect as bio-inoculants for improving tomato growth in different soil types. Besides these, the enriched K content in the post-harvest soils may help the growth of subsequent crops in sustainable agriculture.
