This question was assessed by excluding all the patients that presented at least one modifiable risk factor unrelated to HIV (obesity, metabolic syndrome, hypertension, cholesterol above 240mg/dL and smoking) in order to check whether some factor related to HIV could be masked.
This has implications for changing the modifiable training environment to achieve a desired effect (e.g., increased intensity, frequency, or duration), or excluding people who demonstrate a poor response to reduce treatment costs and consumer disappointment.
In addition, a recent statement from the American Thoracic Society and the European Respiratory Society defined severe asthma as being difficult to control with treatment after excluding 'modifiable factors, such as poor adherence, smoking and comorbidities' (Reddel et al., 2009).
Secondly, a study should measure one or more potentially modifiable determinants of ecstasy use-related behaviour; that is, an antecedent that could be influenced potentially by health promotional interventions (excluding for example demographics, personality, etc).; for a list, see chapter 7 of Bartholomew et al. [ 8].
Furthermore, the developed algebraic model is capable of representing job and resource unavailability, technological constraints, alternative process plans, and is easily modifiable to include new jobs and exclude finished jobs.
Exclusion of early deaths from analysis, while partially accounting for survivorship bias, excludes the key subpopulation with the highest, and perhaps modifiable, mortality.
In this review, 'South Asian' refers to individuals of Indian, Pakistani or Bangladeshi descent with non-modifiable factors (genetic variations and asthma phenotypes) excluded.
Consequently, other known risk factors that are modifiable but did not fall under these categories were excluded (e.g. obesity, type 2 diabetes, hypertension, depression, traumatic head injury etc).
We chose to exclude this population because admissions of this frequency are often influenced by physical and psychological comorbidity or social circumstances or are indicative of the proximity of end of life 30 and as a result would be less modifiable by an exercise intervention.
