Ramy czasowe: From Baseline up to Week 48 or Week 72 (for participants with Genotype 2/3) or up to Week 72 (for participants with Non-Genotype 2/3)
Participants were assigned a score equal to the number of times their dose of antiviral therapy (peginterferon or ribavirin) was reduced (0=no dose reductions [DRs]; 1=one DR; 2=two DRs; 3=three DRs; >3=more than three DRs). Where possible, every effort was made to maintain the recommended dose of antiviral therapy for the treatment duration in the DB Phase. However, where dose modification of antiviral therapy was required due to safety concerns, it was performed by the Investigator as per the region-specific product labels of peginterferon and ribavirin.

Ramy czasowe: From Baseline up to Week 48 or Week 72 (for participants with Genotype 2/3) or up to Week 72 (for participants with Non-Genotype 2/3)
The assigned dose in the DB Phase of peginterferon alfa-2a was 180 micrograms (mcg). For peginterferon dose modification, downward adjustments in one level increments was considered. The lowest dose of peginterferon alfa-2a that was allowed to be administered was 45 mcg. Where dose adjustment was required for moderate to severe adverse reactions (clinical and/or laboratory), an initial dose reduction to 135 mcg was generally adequate. In some cases, a dose reduction to 90 mcg or 45mcg was necessary. Dose increases toward the original dose were considered when the adverse reaction was resolved.

Ramy czasowe: From Baseline up to Week 48 or Week 72 (for participants with Genotype 2/3) or up to Week 72 (for participants with Non-Genotype 2/3)
There are two genetic variants (rs12979860 and rs8099917) mapping near IL28B associated with both interferon-induced SVR and spontaneous HCV clearance. Genotyping of the IL28B polymorphisms (rs12979860 and rs8099917) was conducted. IL28B genotype distribution by response to antiviral therapy (SVR and RVR) for both treatment arms was assessed. The effect of genotype was tested by comparing participants that carried 2 copies of the IL28B favorable response allele versus the others (recessive model). Genotypes at rs12979860 were coded as: CC=1, CT or TT=0; rs8099917 was coded as TT=1, GT or GG=0.

A cataract event is defined as an event ascertained to be a cataract (opacity or cloudiness of the lens of the eye, causing impairment of vision) by at least one of the CEC members (comprised of expert ophthalmologists who provided objective medical review of the blinded ophthalmic data). Per the CEC, cataract events were categorized as: (1) Cataract Progression (CP; progression of cataracts present at BL); and (2) Incident Cataract (IC; development of new cataracts). One eye=unilateral; both eyes=bilateral.

Normal, all ECG parameters within accepted normal ranges. Abnormal, ECG finding(s) outside of normal ranges. CS, ECG with a CS abnormality that meets exclusion criteria. NCS, ECG with an abnormality not CS or meeting exclusion criteria, per Investigator, based on reasonable standards of clinical judgment.

Ramy czasowe: End of Treatment (up to Week 52); and 24-week FU (up to Week 72)
Duplicate 12-lead ECGs were required at Screening/BL, Antiviral BL, and at 12 weekly intervals during the study. The number of participants with a CS or a NCS change from baseline in ECG status was reported, as determined by the Investigator based on a reasonable standard of clinical judgment. "Not applicable" indicates that information was not provided by the investigator on whether the change from baseline ECG was CS or NCS.
