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

Ustilago maydis is a basidiomycete fungus that causes common smut in maize, serving as a model system for studying smut fungi and biotrophic pathogens. Reliable quantification of fungal biomass in planta facilitates tracking fungal proliferation and disease development, evaluating fungal mutant virulence, and assessing host resistance. Traditional methods such as symptom scoring or microscopy after staining are semiquantitative and prone to subjectivity. In this chapter, a DNA-based quantitative real-time PCR (qPCR) assay for sensitive and reproducible measurement of U. maydis biomass in infected maize tissues is described, based on the relative amplification ratio of a fungal gene to a maize reference gene. This assay provides a robust and quantitative tool for investigating fungal virulence and plant resistance.
