Wejse et al developed the TBscore for use in clinical settings with few resources. The TBscore at the end of treatment correlated with subsequent survival. The authors are from Aarhus University in Denmark.

where:
• The normal mid-upper arm circumference would be affected by age and gender as well as malnutrition. Note that the same cutoff is used for men and women.
total score =
= SUM(points for all 11 parameters)
Interpretation:
• minimum score: 0
• maximums score: 13
• The higher the score the more severe the tuberculosis.
• Clinical improvement was defined as either being severity class I or have a drop in score > 25%.
