Conversely, many recently published studies have found a significant decrease in mortality in septic shock [ 5– 7], or in severe respiratory failure requiring invasive mechanical ventilation (IMV) [ 8]; therefore, it is reasonable to assume that mortality due to severe pneumonia, especially when complicated with septic shock, may have decreased in the last few years.
Sorensen et al. found a significant decrease in mortality for those who achieved abstinence [ 7], but in the present study, it was not known whether patients completed or discontinued the detoxification programme.

Two of these studies are included in the meta-analysis of the US Preventive Services Task Force [ 7], which confirmed the decrease in the incidence of myocardial infarction, but found no significant differences in mortality reduction.
In urban areas, a significant decrease in mortality was found in five cities compared to only one rural district.
A statistically significant decrease in mortality was found in the states of Rio Grande do Sul, Rio de Janeiro and São Paulo (Table 2).> -wrap-foot> AAPCeviaverage annualverage annual percent change; APC annual percent change.

Mortality was significantly reduced in men but not in women; however, for a subset of persons there were updated data and an analysis of these data found a non-significant effect of smoking in males but a significant decrease in mortality among women; however, this was based on only 16 cases.
