Change From Baseline in PRISM Over TimeSecondary· 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.

Change From Baseline in FACIT-F Scale Over TimeSecondary· Baseline, EoT (treatment period was 12 or 24 weeks), 12 and 48 weeks after EoT
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.

Adverse events — posted to ClinicalTrials.gov
Time frame: up to 30 days post treatment (treatment period was 12 weeks or 24 weeks).
Reporting threshold: 5%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
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.
