Lipoxin A4 levels predict site-specific clinical improvements post scaling and root planing and correlate negatively with periodontal pathogens in severe periodontitis

Table 4 Relationships between the increase in LXA4 concentration and future PD improvements in patients with severe periodontitis after adjusting for gender, age and plaque accumulation

LXA4 increase in concentrations (per 100 pg/µl)	ΔPD ≥ 2 mm at 3 m		ΔPD ≥ 2 mm at 6 m
LXA4 increase in concentrations (per 100 pg/µl)	OR (95%CI)	p-value	OR (95%CI)	p-value
3 m	1.193 (0.858, 1.660)	0.294	-	-
6 m	-	-	2.684 (1.189, 6.057)	0.017

Abbreviations: m, month; ΔPD, PD reduction from baseline to the indicated time point after SRP
ΔCAL, CAL gain from baseline to the indicated time point after SRP
OR (95% CI), odds ratio (95% confidence interval)
