Data are presented as n (%) unless otherwise stated. Risk assesment of acquiring NTM growth and colonisation. SES: socioeconomic status. #: comparison between three groups; : adjusted odds ratio for any growth (composite of single growth and colonisation); +: significant difference after Bonferroni correction between no NTM and NTM single growth; §: significant difference after Bonferroni correction between NTM single growth and NTM colonisation. Bold indicates statistically significant odds ratios.
