Treatment-emergent depression and anxiety between peginterferon alpha-2a versus alpha-2b plus ribavirin for chronic hepatitis C.
Observational study in BMC psychiatry, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02943330 (Relation Between Depression, Genes, Cytokines, Chronic Fatigue, Physical Illnesses and Quality of Life), which is not on this map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundThis study investigates differences in depression and anxiety between patients with chronic hepatitis C who are treated with peginterferon alpha-2a (PegIFN-α-2a) plus ribavirin and those who are treated with peginterferon alpha-2b (PegIFN-α-2b) plus ribavirin.
methodsIn this 24 week, non-randomized, observational, prospective study, 55 patients with chronic hepatitis C were treated with PegIFN-α-2a plus ribavirin (Group 1), and 26 patients were treated with PegIFN-α-2b plus ribavirin (Group 2). All patients underwent assessment using the Hospital Anxiety and Depression Scale (HADS) at the baseline and at weeks 4, 12 and 24. Patients with depression scores (HADS-D) ≥ 8 and anxiety scores (HADS-A) ≥ 8 were defined as having depression and anxiety, respectively. The factors that were associated with depression and anxiety during the 24 week antiviral treatment were determined.
resultsDuring the 24 week antiviral treatment, the proportion of patients with depression significantly increased over time in both groups (Group 1: p = 0.048; Group 2: p = 0.044). The proportion of patients with anxiety did not significantly change during the follow-up period in either group. Incidences of depression or anxiety did not differ significantly between Group 1 and Group 2. A history of alcohol use disorder was an independent predictor of depression at week 12 (p < 0.001) and week 24 (p < 0.001), and a poor virological response to treatment was associated with depression at week 24 (p = 0.029). Patients who had more physical comorbidities were more likely to suffer from anxiety at week 12 (p = 0.038).
conclusionsThis study did not identify significant differences in depression or anxiety between in patients with chronic hepatitis C who underwent a 24 week antiviral treatment regimen with PegIFN-α-2a plus ribavirin and those who underwent a regiment with PegIFN-α-2b plus ribavirin. Future research with larger samples and a randomized, controlled design are required to verify the findings in this study.
