Fig. 3From: Sputum lipoarabinomannan (LAM) as a biomarker to determine sputum mycobacterial load: exploratory and model-based analyses of integrated data from four cohortsChange from baseline correlation between log10 LAM concentrations and log10 CFU concentrations in sputum samples. Note: Red solid line depicts line of unity, blue solid line represents a smoothing spline fit to the observed data, gray shaded area depicts the 95% confidence interval of the spline fit. CFB, change from baseline; CFU, colony-forming units; LAM, lipoarabinomannan; log10, 10 logarithmBack to article page
