1 · What the graph read from it

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.

2 · The registry

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

Introduction: Soil salinization is a major constraint to agricultural productivity on Hainan Island, China, as it reduces soil fertility and disrupts microbial community structure. Nano-modified biochar has emerged as a promising strategy to improve soil quality and microbial resilience under saline conditions. This study evaluated the effects of iron- and zinc-modified nano-biochar on soil physicochemical properties and microbial communities in saline and non-saline paddy soils. Methods: A pot experiment was conducted using four treatments: control (CK), pristine biochar (BC), iron-modified biochar (FeBC), and zinc-modified biochar (ZnBC). Soil physicochemical properties, enzyme activities, microbial biomass, and bacterial and fungal community composition were analyzed using standard chemical assays and high-throughput sequencing techniques. Results: Application of nano-modified biochar significantly increased soil organic matter, soil organic carbon, and the availability of macronutrients (N, P, and K). FeBC and ZnBC enhanced microbial biomass carbon and nitrogen as well as urease and β-glycosidase activities in saline soil. Nano-biochar treatments altered microbial community composition, increasing the abundance of salt-tolerant bacterial phyla such as
