Dimensionless Parameters Define Criteria for Optimal Flow Velocity in Enhancing Chemotactic Response toward Residual Contaminants in Porous Media.
Article in Environmental science & technology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Chemotactic bacteria may overcome challenges posed by nonaqueous-phase liquid (NAPL) contaminants of low solubility in groundwater and limited bioavailability in tight pores by preferentially migrating to NAPL sources. We explored the transport of chemotactic bacteria to NAPL ganglia at varying pore water velocities in a dual-permeability microfluidic device and using computer-simulated solutions of transport equations. In our experiments, bacteria exhibited a chemotactic response toward NAPL ganglia at the junctures of low- and high-permeability regions (i.e., micropockets), and the extent of retention initially increased with velocity and then decreased at the highest velocity. A dimensional analysis revealed that maximum accumulations occurred at moderate values of the Péclet number
