Agee association of protein levels. The boxplots include three age groups of women: < 45 years of age, 45–55, and > 55 years of age for LHB (top row) and FSHB (bottom row). The left plots show qDBS from multiplex assays, while the right plots show plasma analyzed at the clinical chemistry laboratory. The number of subjects with protein levels above LOD is shown above the respective box. Nominal p-values were calculated using Wilcoxon tests and displayed as * p < 0.05; ** p < 0.01; *** p < 0.001; **** p < 0.0001
