Systemic mycobacterial load is associated with outcome in HIV-associated tuberculosis but is poorly defined. We used latent variable modelling to characterise HIV-associated TB mycobacterial load. Mycobacterium tuberculosis detection tests on urine and blood, but not sputum, showed substantial co-variance, and were strongly correlated with host inflammation and mortality.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
