Evaluation of serum samples in long cryopreservation for SomaScan proteomics and sex differences in elderly Japanese adults.
Observational study in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Many biobanks store biological samples and use them for various analyses, including proteomics. Therefore, it is necessary to consider the denaturation of target proteins during long-term storage. We analyzed 16-year-old cryopreserved serum samples using the SomaScan platform, a novel proteomic assay, to determine whether adiponectin and resistin concentrations were consistent with those measured in our previous studies using a different platform. The results suggested that long-term cryopreserved serum samples could be used for future studies of at least adiponectin and resistin, which are closely related to the pathophysiology of diabetes, cardiovascular disease, and other metabolic diseases. Therefore, 7,289 SomaScan-assayed circulating proteins were compared between 20 men and 20 women aged ≥ 50 to determine sex differences. In total, 20 serum proteins showed significant sex differences. Of these, proteins that showed a more than two-fold difference in concentration between sexes contained heterodimeric forms of gonadotropic proteins such as CGA|FSHB, CGA|CGB3|CGB7, and CGA|LHB, which are the biologically active forms of these hormones. The present study is the first to report the possibility of using long-term cryopreserved serum samples for the SomaScan assay, and the results show that the SomaScan assay may be useful for analyzing sex differences focusing on gonadotropic hormones.
