How long is DOTS for TB?

Excuse me, could you please clarify something for me? I'm trying to understand the duration of DOTS for TB treatment. How long does the DOTS therapy typically last for tuberculosis? I've heard it's a crucial part of the treatment process, but I'm not entirely sure about the exact duration. Could you please elaborate on this matter? I'm quite curious to know more about it. Thank you for your time and assistance in this matter.
