Physicochemical Pathways Governing Sludge Formation in Tank Farm Storage: Comparative Analysis of Crude, Brine, and Sludge.
Article in ACS omega, 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
Petroleum sludge accumulation in crude oil storage terminals leads to significant operational inefficiencies impacting tank capacities and unplanned maintenance shutdowns. To understand the mechanistic origin of sludge formation, we performed an integrated physicochemical characterization of the source crude, tank farm crude, associated brine, and tank bottom sludge. The source and tank farm crude oils have measurable differences in their properties such as density, viscosity, SARA fractions, and metal content, which indicates compositional evolution during midstream transport. The sludge sample contains ∼30 wt % inorganic solids, comprising sand, corrosion products, and carbonate scale; ∼53.5 wt % hydrocarbons; ∼47 wt % asphaltenes; and ∼16.5 wt % associated water. Rheological measurements show pronounced non-Newtonian behavior, with a yield stress of ∼10
