Table 1 Characteristic of study subjects

From: Effects of ultrafine particles on the allergic inflammation in the lung of asthmatics: results of a double-blinded randomized cross-over clinical pilot study

Characteristic of study subjects N = 12
Female sex − no. (%) 4 (33.3)
Age − years 38 [34.2;41.5]
Body weight - BMI 25.8 [23.8;27.8]
FEV1 − % predicted value 96.4 [88.8;103.9]
Methacholine PC20 − mg/ml 1.3 [0.3;5.3]
IgE − IU/ml 423.8 [79.0; 768.5]
Segmental allergen dose − SQE 541.8 [237.2;846.3]
  1. Absolute and relative frequencies of women, mean of study subjects and corresponding 95%-confidence interval for all other baseline characteristics. Confidence interval for metacholine concentration is computed with logarithmic transformation; BMI: Body mass index, FEV1: forced expiratory volume in 1 second, Methacholine PC20:metacholine concentration to induce a 20% decrease in FEV1, IgE: total serum IgE (immunonglobulin E), SQE: standard quality unit.
