From: Smoking induces increased apoptosis in osteoblasts: changes in bone matrix organic components

Expression of IL-1β, IL-6 and TNF-α in bone homogenates of non-smokers, former smokers and smokers (A) n = 13, n = 16, n = 25 respectively), (B) n = 16, n = 18, n = 25 IL-6 respectively) and (C) n = 16, n = 22, n = 25 respectively). Significant increased were found in former smokers and smokers compared with non-smokers in IL-1β (*p = < 0.001, Dunn's Test), IL-6 (*p = 0.001, Dunn's Test) and TNF-α (*p = < 0.001, Dunn's Test). Values were expressed as mean ± SE.
