1 · What the graph read from it

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.

2 · The registry

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

Understanding oxidized uranium [U(VI)] reactions with natural organic matter (NOM) is necessary to predict the solubility and mobility of U and NOM in waters from organically rich geologic uranium deposits influenced by natural and anthropogenic processes. Here, we investigated the changes in the chemical composition of NOM resulting from its reaction with U(VI) under acidic and neutral pH under controlled laboratory conditions. We employed a multianalytical approach, including X-ray photoelectron spectroscopy (XPS), Fourier transform ion cyclotron resonance-mass spectrometry (FTICR-MS), transmission electron microscopy (TEM), and X-ray absorption spectroscopy (XAS). Results revealed that U(VI) reaction at acidic pH led to a decrease in the relative content of alcohols, carboxylic functional groups, and compounds with high O/C ratios in NOM. Our integrated analyses suggest that NOM's molecular composition is altered by two primary mechanisms: (1) selective aqueous complexation of U with alcohol and carboxylic groups in NOM and (2) U adsorption onto particulate organic matter (POM). These findings provide insights into NOM chemical transformations due to U interactions under pH conditions relevant to acid mine drainage, natural geologic deposits, and surface waters affected by legacy uranium mining.
