HIV infection stratified by gender and region of Nepal.

<p>M: male, F: female, 95% CI: 95%-confidence interval. n = 354. Gender difference (male vs. female) for HIV non-significant, χ²-p = 0.18. Regional difference (Nepalgunj vs. ‘other’) for HIV non- significant χ²-p = 0.07.</p><p>HIV infection stratified by gender and region of Nepal.</p

HCV-genotypes stratified by gender and region.

<p>M: male, F: female, “undef” = undefined, n = 200. Gender difference for GT1 vs. 3 non-significant χ²-p = 0.34. Regional difference for GT1 vs. 3 non-significant χ²-p = 0.38.</p><p>HCV-genotypes stratified by gender and region.</p

Phylogenetic tree of the 5 UTR region of HCV.

<p>The tree is generated by the neighbour-joining method in MEGA 6. The symbol indicates the reference sequences. The first character of the code indicates the origin of the sample (K: Kathmandu, L: Lalitpur, (Central Region), B: Biratnagar (Eastern Region), and N: Nepalgunj (Western Region).</p

Rate of spontaneous clearance stratified by age and HIV status.

<p>Rate of spontaneous clearance of HCV is associated with age (spontaneous clearance associated with age: χ²-p<0.001) and HIV status (spontaneous clearance associated with HIV-status in “all” patients: two-sided Fischer’s Exact p = 0.03, error bars show 95% CI).</p

Rate of spontaneous clearance stratified by HBsAg-status.

<p>Spontaneous HCV clearance among people living with HBsAg is significantly higher versus people who are negative for HBsAg. (Two-sided Fisher exact p<0.001, error bars show 95% CI).</p

Percentage of frequencies of HIV and HCV mono- and co-infection.

<p>At 3.3%, HIV mono-infection is a comparatively rare constellation whereas HIV/HCV co-infection is found in 18.1% of all participants (n = 397).</p
