Blood bacterial load (determined by qPCR and expressed as 16S rRNA gene copies per μl) and zonulin level (determined by ELISA test) are also shown. OS01-43, consecutive anonymized coding of the older subjects included in the study. 16S rRNA g.c., 16S rRNA gene copies; I and II, first and second set of blood samples analyzed, respectively; n.a., data not available due to missing sample.
