Mustard oil-derived carbon dots for ultra trace Pb
Article in RSC advances, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Water-soluble blue fluorescent carbon soot-carbon dots (CS-CDs) were synthesized using mustard oil through a flame deposition method. This work investigates the effect of a confined combustion environment on particle formation. While particle size remained same even when the container volume was increased fourfold, a significant increase in defect density was observed. An intermediate volume of 1 L produces blue-shifted emission at 422 nm, compared to 430 and 428 nm for 0.5 L and 2 L, respectively, upon excitation at 350 nm. Microscopic and spectroscopic analyses revealed that as-synthesized CS-CDs possess a partially graphitized nanocrystalline core embedded within a highly disordered, defect-dense amorphous matrix. CS-CDs obtained from within the 2 L volume demonstrated sensitive and selective detection of Pb
