In comparison to the findings of some of the above studies, tuberculosis, multiple organ involvement (≥3 organ systems) and in-hospital mortality were associated with a longer LOS on univariate analysis, while there were no significant differences with regards to age, gender, low CD4 cell count (<100 cell/mm3), use of ART and Pneumocystis jirovecii pneumonia. Here, CD4 is linked to tuberculosis.
