SAF Z-scores according to presence of anemia (A), severity of anemia (B), age and presence of anemia (C) and the type of anemia (D). Mild anemia was defined as a hemoglobin concentration between 11.0 and 12.99 g/dL in males and between 11.0 and 11.99 g/dL in females, whereas moderate and severe anemia were defined as hemoglobin concentration between 10.0 and 10.99 g/dL and <10.0 g/dL respectively. Data on the type of anemia were available for anemic individuals aged ≥60 years. Bars represent mean values, with error bars representing the standard error. SAF = skin autofluorescence.
