Fig. 4From: Calprotectin and cross-linked N-telopeptides of type I collagen levels in crevicular fluid from implant sites with peri-implant diseases: a pilot studyCorrelation between NTx amounts and PD or BL rates. a The correlation between PICF NTx amounts and PD was evaluated in PICF samples from peri-implant disease and healthy groups (n = 74, ρ = 0.434, P < 0.001). b The correlation between PICF NTx amounts and BL rates (%) was evaluated in PICF samples from peri-implant disease and healthy groups (n = 74, ρ = 0.570, P < 0.001)Back to article page
