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

key messageCalcium oxide nanoparticles (CaONPs) effectively mitigate vanadium-induced toxicity in rapeseed by enhancing plant growth, photosynthesis, antioxidant defense, and nutrient uptake while reducing vanadium accumulation. Among variety of heavy metals (HMs), vanadium (V) is an important and most ruinous metal found in the earth crust. Use of nanoparticles is emerged as an important strategy with promising discretions for the solution of HMs induced drastic effects on plants. This study intended to determine how calcium oxide nanoparticles (CaONPs) could alleviate V stress in rapeseed (Brassica napus L.) plants through modulation of physiological parameters, activation of antioxidant defense systems, and regulation of stress-responsive gene expression. A greenhouse experiment was performed and utilized spherical CaONPs and size 8-20 nm as foliar and soil application to mitigate the V toxicity in rapeseed plants. The three levels of CaONPs (10,20, and 30 mg L
