From: The effect of APN, hs-CRP and APN/hs-CRP in periodontitis with DAA
The ratio of APN/hs-CRP signified the balance between anti-inflammation and pro-inflammation. The results revealed, at T1, significantly lower (p < 0.05) ratio of APN/CRP in D group, but no significant difference (p > 0.05) in group B, C group as compared to A group; at T2, compared to A group, the ratio was significantly lower (p < 0.05) in both B and D group. However, C group demonstrated no difference (p > 0.05); the ratio was significantly lower (p < 0.05) in the B, C, D group at T3, T4, T5, compared to A group. Overall, with the disease progression, the ratio of the B group failed to reflect any significant downward trend, whereas, C, D group manifested a gradual downward trend
