Table 2 Mean NIP and mean DIN for the four elevation sites on Chaumont Mountain

Site	NIP^a (%)	NIP 95% CI	DIN1^b	DIN1 95% CI	DIN2^b	DIN2 95% CI
Low	15.3	15.0–15.6	2969	1882–4684	8.1	5.2–12.8
Medium	11.9	11.6–12.2	1775	1125–2800	4.9	3.1–7.7
High	10.8	10.4–11.1	983	623–1552	2.7	1.7–4.3
Top	12.7	12.3–13.1	246	156–388	0.7	0.4–1.1

Values in Table 2 are presented as the means and their 95% confidence intervals (CIs). These means and 95% CIs were calculated from linear models that only contained the explanatory factor of elevation site.
^aThe NIP is the percentage of I. ricinus nymphs infected with B. burgdorferi s.l..
^b The DIN is the number of questing B. burgdorferi s.l.-infected I. ricinus nymphs per 100 m². The DIN is given as the total for the whole year (DIN1) or the daily average (DIN2). DIN1 is calculated by multiplying the DON by the NIP. DIN2 is calculated by dividing the DIN1 by 365 days.
