CD36⁺ red cells and their relationship to age and F-cell and non–F-cell fractions.

Correlation between CD36⁺ red cells and age (A) and F-cell number (B) from 40 patients with SS disease are presented. Red cells from 17 patients with SS disease were analyzed for CD36⁺ F cells (C) and CD36⁺ non–F cells (D) and their respective relationships to F-cell and non–F-cell fractions. The solid line represents the linear-regression fit to the data, and the dotted lines represent the 99% confidence interval curves.
