The JHU researchers prospectively examined changes in fibrosis stage between paired liver biopsies in 67 coinfected patients. Of the 67 subjects, six were excluded due to cirrhosis on the first biopsy. The median age of group was 44 years, and 75% of the subjects were men. A total of 86% had CD4+ cell counts of less than 200 cells/mm3, and the same number of subjects were receiving antiretroviral therapy. Twenty-seven percent of the patients abused alcohol. The median time between biopsies was 2.84 years (interquartile range, 2.05 - 3.41 years).

Among the four paper formation assessment methods, i.e., coefficient of variation, varience (S^2), M/K formation index, and modified all-pairs score, the COV and look-through judgements are most affected by mean light absorbance. Under similar mean light absorbance renditions, all four methods gave similar results.
