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
Salinity stress disrupts plant physiology and inhibits plant growth. While microorganisms and silicon (Si) are known to mitigate salt stress, their combined effect with soil fauna like earthworms is underexplored. This study examined the effects of Si nanoparticles (Nano-Si: 0, 100, 200 mg kg⁻¹) and biological treatments (silicate-solubilizing bacteria (SSB) Bacillus subtilis (SSB1), Pseudomonas fluorescens (SSB2), earthworm Eisenia fetida (EWs)), and their combinations, on wheat under three salinity levels (0.97, 5, and 8 dS m⁻¹). Salinity reduced biomass, chlorophyll, relative water content (RWC), and potassium uptake, while increasing sodium, electrolyte leakage (EL), lipid peroxidation (MDA), and antioxidant enzyme activity. Nano-Si at 200 mg kg⁻¹ alleviated stress, increasing shoot dry weight (21.5%), chlorophyll (32.8%), and RWC (13.3%), while reducing MDA (17.3%) and EL (12.4%). SSB inoculation similarly improved growth and oxidative stress markers. The Nano-Si and SSB combination was most effective, enhancing the K⁺/Na⁺ ratio and reducing oxidative damage. Earthworms, especially with SSB, further improved soil conditions, increasing root length (up to 17.4%) and shoot Si concentration. We conclude that synergistic application of Nano-Si and SSB effectively enhances wheat salinity tolerance by improving photosynthesis, ion homeostasis, and antioxidant defense, with earthworms providing additional benefits for root development and Si uptake.
