The Impact of Sodium Hexametaphosphate Use in Soil Fractionation Protocols on Downstream Mineral Analyses.
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
Sodium hexametaphosphate (NaHMP) is a common chemical dispersant used in soil analytical methods such as the fractionation of mineral-associated organic matter (MAOM) from bulk soil; however, its effect on downstream mineral analyses is not well understood. This study examined how pretreatment with NaHMP affected subsequent metal speciation analyses in soil studies. Emulating MAOM fractionation protocols, a simulated physical fractionation was performed by exposing technical replicates of three Florida soils with variable clay and organic matter content to a 0.5% NaHMP solution. NaHMP-treated and control soils were then sequentially extracted into exchangeable, carbonate-bound, Fe-Mn oxide-bound, organic matter-bound, and residual metal fractions using a modified Tessier extraction protocol. To assess treatment effects, metal concentrations were compared using a mixed-design factorial ANOVA. Tests of simple main effects indicated no significant difference between treatments (
