Mechanistic and kinetic modeling of cadmium and lead phytoextraction by Madagascar Periwinkle [Catharanthus roseus (L.) G.Don] in battery waste contaminated soil.

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
Remediation of heavy metal-contaminated soils is critical due to their persistent toxicity and threat to food security and ecosystem health. Therefore, a study was conducted during September to November 2024 to assess the phytoextraction potential of Madagascar Periwinkle (Catharanthus roseus) for cadmium (Cd) and lead (Pb) in soils spiked with varying concentrations of battery scrap waste (BSW: 0, 1, 2, 3, and 4% w/w). A hybrid mechanistic-kinetic (HMK) model was developed by the integration of the Freundlich isotherm and Michaelis-Menten equations to predict bioavailable heavy metal concentrations and uptake by plants. The results showed that C. roseus had higher Cd and Pb accumulation in roots compared to shoots, with maximum concentrations of 21.504 mg/kg Cd and 43.123 mg/kg Pb observed at 4% BSW. However, increasing contamination levels significantly reduced metal removal efficiency (%), as evidenced by bioconcentration factor (BCF) and translocation factor (TF) values. Also, increasing the BSW dose significantly (p < 0.05) reduced C. roseus growth, reducing plant height, root length, biomass, chlorophyll, and carotenoid content due to heavy metal toxicity. On the other hand, Freundlich coefficients (K
