Advanced Proteomic Profiling Demonstrates Clinical Utility of Patient-Centric, at-Home Dried Blood Sample Collection.
Article in Journal of proteome research, 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
Patient-centric, at-home, dried blood collection can increase compliance, reduce cohort size, decrease shipping costs, and open the door for broader applications of affinity proteomics. Dried blood samples from 16 individuals, collected by Tasso M20 "smart" devices, were analyzed by the SomaScan Assay using conditions modified for this new matrix. These assay results were compared to plasma and serum from the same donors. The cross-section of proteins that can be measured in both plasma and dried blood was determined. Complete blood counts (CBCs) were also taken from these donors. We generated models to predict these counts based on SomaScan Assay measurements. Over 800 proteins can be measured in both plasma and DBS. These proteins are actively secreted by cells or found on cellular surfaces. The remainder of the SomaScan Assay menu contains information on the cellular component of whole blood. Models generated from DBS data can more accurately predict complete blood counts than those generated from plasma.
