Quadratic latent growth models for three group comparisons of weight change in TB patients over time according to regimen with bootstrap sample of 1000 (a) regimen 1 (b) regimen 2 (c) regimen 3.

Legend: i - intercept of quadratic latent growth model of weight change in TB patients. s - slope of quadratic latent growth model of weight changes in TB patients. q - quadratic factor of latent growth model of weight changes in TB patients. wt0 - weight of TB patients in kilograms at the initial stage of anti TB treatment. wt2 - weight of TB patients in kilograms at 2^nd month of anti TB treatment. wt4 - weight of TB patients in kilograms at 4^th month of anti TB treatment. wt6 - weight of TB patients in kilograms at 6^th month of anti TB treatment.
