Changes of vessel diameter after i. c. infusion of acetylcholine (ACh D2: 36 μg/min) compared with baseline diameter.

n = 16
CP IgG < 1:16 (CP negative)
CP IgG ≥ 1:16 (CP positive)

Increase of vessel diameter
2 (33 %)
7 (70 %)
No increase of vessel diameter
4 (67 %)
3 (30 %)

The two groups were allotted according to their Chlamydia pneumoniae (CP) IgG serum titer. Two-tailed exact Fisher's test did not show any significant difference between both groups (p = 0.302).
