Water Diffusion and Uptake in Injectable ETTMP/PEGDA Hydrogels.
Article in The journal of physical chemistry. B, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Differential scanning calorimetry (DSC) and pulsed field gradient spin echo nuclear magnetic resonance (PFGSE NMR) were used to characterize water in hydrogels of ethoxylated trimethylolpropane tri-3-mercaptopropionate (ETTMP) and poly(ethylene glycol) diacrylate (PEGDA). Freezable and nonfreezable water were quantified using DSC; water diffusion coefficients were measured using PFGSE NMR. No freezable water (free or intermediate) was detected from DSC for hydrogels of 0.68 and greater polymer mass fractions. Water diffusion coefficients, from NMR, decreased with increasing polymer content and were assumed to be weighted averages of free and bound water contributions. Both techniques showed decreasing ratios of bound or nonfreezable water mass per polymer mass with increasing polymer content. Swelling studies were used to quantify the equilibrium water content (EWC) to determine which compositions would swell or deswell when placed in the body. At 30 and 37 °C, fully cured, non-degraded ETTMP/PEGDA hydrogels at polymer mass fractions of 0.25 and 0.375, respectively, were shown to be at EWC.
