Diabetes. 2022;71:1591-1596. https://pubmed.ncbi.nlm.nih.gov/35499624/Brief Summary: This cross-sectional study compared trends in plasma C-peptide decline in 4,076 young people with type 1 diabetes (T1D), with trends in beta-cell loss in 235 pancreas donors. As expected, C-peptide declined over time, and this was particularly marked in children with T1D younger than 7 years. Of interest, p...
