Assessment of quaternary aquifer pollution sensitivity using modified DRASTIC models around stressed Canal in Eastern Nile delta, Egypt.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Groundwater is generally less prone to contamination than surface water; however, pollutant infiltration can occur due to aquifer characteristics and anthropogenic land use (LU) changes. This study presents the first DRASTIC-based groundwater contamination risk (GwCR) framework for stressed aquifers around the Ismailia Canal, a newly developed artificial canal in Egypt. It evaluates the standard DRASTIC, Pesticide DRASTIC, DRASTIC-Lu, and Pesticide DRASTIC-Lu models, along with their modified versions, using Single Parameter Sensitivity Analysis (SPSA) and GIS techniques. SPSA identified the following parameter weights for the pesticide-specific DRASTIC model: D > S > T > A > I > C > R. One- Map Removal Sensitivity Analysis (MRSA) analysis showed the Pesticide DRASTIC model was most sensitive to net recharge (1.36%) and soil media (1.0%), with moderate sensitivity to the vadose zone (0.65%), topography (0.45%), and hydraulic conductivity (0.42%). Excluding key parameters, particularly D, A, and S, caused significant variability, impacting vulnerability assessments. The Pesticide DRASTIC
