When compared to skin spacers, the proportion of shared spacers in saliva over time in each subject was highly significant (p < 0.005 in all subjects for SGII and SGI spacers) (Additional file 1 : Table S4).
When compared to skin spacers, the proportion of shared spacers in saliva over time in each subject was highly significant (p < 0.005 in all subjects for SGII and SGI spacers) (Additional file 1 : Table S4).
While the results did not reach statistical significance for Subject#4, the trends in the proportions of intra-subject shared spacers between skin and saliva exceeded inter-subject comparisons substantially (86% vs 57% for SGI spacers and 58% vs 35% for SGII spacers).
