Relationship of 348T>C Genotype to PMN Chemotactic Activity and Relative FPR1 Expression in a Pool of All Case and Control Subjects

Genotype Group	Chemotaxis activity to 30 nM fMLF^*	Fold increase in FPR1 expression^‡

348 C/C	89.3 ± 2.8^†	1.92
	(n = 30)	(n = 32)

348 T/C	99.3 ± 4.0^†	2.93
	(n = 23)	(n = 26)

348 T/T	66.2 ± 4.0^†	1.32
	(n = 5)	(n = 5)

Data are reported as mean ± SEM. Differences among the groups in this column are statistically significant (P < 0.001, ANOVA). Within this column, like superscripts indicate values that are significantly different (P <0.05, Holm-Sidak test)

^‡

Transformed values (ΔΔCt) represent n-fold change in FPR1 expression relative to baseline. Variability is not shown since the transformed data is positively skewed and can be misleading. Differences among the groups in this column are not statistically significant (P =0.26, Kruskal-Wallis ANOVA on ranks).
