PD-L1 correlates with chemokines and cytokines in gingival crevicular fluid from healthy and diseased sites in subjects with periodontitis

Table 1 Ranges and means (SEM) of PD-L1 values

Status and number of subjects	Total number of healthy and diseased sites	Subjects with healthy sites	Subjects with diseased sites	Range^a	Mean (SEM)
Periodontally diseased subjects^b
20	37 healthy sites	19		(0.16, 31.65)	7.49 (2.04)
20	53 diseased sites		20	(0.04, 21.73)	5.44 (1.19)
Periodontally healthy control subjects
12	48 healthy sites	12		(1.28, 11.35)	5.79 (0.92)

^aThis is the minimum PD-L1 value and maximum PD-L1 value for each particular group of interest after averaging together all healthy sites for a subject and all diseased sites for a subject
^bOne periodontally diseased subject did not have samples from healthy sites
