Adjusted negative binomial regression of predictors for number of admissionsa with respiratory conditions and other infections according to HTLV-1 serostatus.

Adjusted negative binomial modeling of predictors for admission to Alice Springs Hospital among 1317 adult Indigenous residents of central Australia, 2005–2010. Excluding patients who died prior to 2005 and those residing outside central Australia for whom admission data was incomplete.a Adjusted for comorbidities (harmful alcohol consumption, diabetes, chronic liver disease, chronic kidney disease, hemodialysis), age, gender and place of residence. Respiratory conditions were also adjusted for smoking and, in the case of asthma, LRTI and pneumonia, for definite or possible bronchiectasis.b The coefficient represents the average change in the number of admissions that is associated with the presence of the predictor variable according to HTLV-1 serostatus.c Identified by ICD-10 AM code. Bronchiectasis was confirmed by high resolution computed tomography chest.d LRTI other than pneumonia.e Identified by ICD-10 AM code with the exception of BSI episodes.f The number of blood cultures that yielded a significant pathogen as defined in methods.Abbreviations: BSI, blood stream infection; COPD, chronic obstructive pulmonary disease; LRTI, lower respiratory tract infection.
