The aim of our study was to determine if these recommendations are followed in Spain, and the factors associated with the use of 3 drugs (standard regimen without ethambutol).

Methodology: Observational, multicenter, retrospective analysis of data from patients diagnosed with TB in practically all Spanish Autonomous Communities between 2007 and 2102.
