Percentage of Participants With Sustained Virologic Response (SVR12) Primary · 12 weeks after the last dose of study drug (treatment period was 12 or 24 weeks)

SVR12 is defined as hepatitis C virus (HCV) ribonucleic acid (RNA) less than the lower limit of quantification (\< 50 IU/mL) 12 weeks after the last actual dose of the ABBVIE REGIMEN.

The number of participants meeting the following SVR12 non-response categories: 1. On-treatment virological failure (breakthrough) defined \>= 1 documented HCV RNA \< 50 IU/mL followed by HCV RNA \>= 50 IU/mL during treatment or failure to suppress (each measured on-treatment HCV RNA value \>= 50 IU/mL) 2. Relapse defined as HCV RNA \< 50 IU/mL at EoT followed by HCV RNA \>= 50 IU/mL post-treatment in participants who completed treatment (\<= 7 days shortened).

Change From Baseline in PRISM Over Time Secondary · Baseline, 12 and 48 weeks after EoT (treatment period was 12 or 24 weeks)

PRISM is a visual quantitative method to assess the perceived burden of suffering due to illness. The distance between the center of the "self" (yellow disk) and the illness disk (red disk) is called "self-illness separation" (SIS) and is measured in cm (range is 0 - 27). The smaller the distance, the higher the burden of suffering.

The FACIT-F Scale is a 13-item questionnaire that assesses self-reported fatigue during the past 7 days and its impact upon daily activities and function. Scores range from 0 - 100, with higher scores indicating a lesser degree of fatigue.

Sponsor's own description

The interferon-free combination regimen of paritaprevir/r - ombitasvir with or without dasabuvir (ABBVIE REGIMEN) ± ribavirin (RBV) for the treatment of chronic hepatitis C (CHC) has been shown to be safe and effective in randomized controlled clinical trials with strict inclusion and exclusion criteria under well controlled conditions. This observational study is the first effectiveness research examining the ABBVIE REGIMEN ± RBV, used according to local label, under real world conditions in Germany in a clinical practice patient population.
