Direct-acting antiviral agent use and gastrointestinal safety in patients with chronic hepatitis C: a pharmacovigilance study based on FDA Adverse Event Reporting System.
Article in International journal of clinical pharmacy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundGastrointestinal adverse drug reactions (GADRs) of direct-acting antiviral agents (DAAs) in patients with chronic hepatitis C are underestimated.
aimThis study aimed to comprehensively evaluate the gastrointestinal safety of DAAs in patients with chronic hepatitis C.
methodThe US FDA Adverse Event Reporting System database was searched for GADR cases reported from 01 to 2012 to 30 September 2021. Twelve DAA types used for hepatitis C virus were included. The top 30 GADRs were assessed based on the use of DAAs, number of cases, and clinical features. A case-non-case disproportionality approach was used to confirm pharmacovigilance signals, whereby reporting odds ratios (ROR) with 95% CI were calculated.
resultsNausea (70.01/1000), diarrhoea (39.10/1000), and vomiting (31.68/1000) accounted for the highest number of cases. The pooled median time-to-onset of the top 30 GADRs was 13 days (Q1-Q3: 2-38) and the proportion of drug discontinuation was 19.17%. The highest number of DAA-related cases involved ledipasvir/sofosbuvir (21.86%), sofosbuvir/velpatasvir (21.77%), and sofosbuvir (13.41%). When DAAs were considered as a class drug, after adjusting for age, sex, concomitant diseases and drugs that potentially induced GADRs, significant RORs for specific GADRs were noted, including abdominal discomfort (1.62, 95% CI 1.32-1.99), constipation (1.54, 95% CI 1.26-1.89), dyspepsia (1.25, 95% CI 1.01-1.55), abdominal distension (1.36, 95% CI 1.05-1.75), faeces discoloured (1.77, 95% CI 1.15-2.73), and gastric ulcer (2.37, 95% CI 1.28-4.41).
conclusionClinicians should have a deeper understanding of GADRs to improve the gastrointestinal tolerance of patients with chronic hepatitis C.
