Effect of Direct-Acting Antiviral Agents on Gastroesophageal Varices in Patients with Hepatitis C Virus-Related Cirrhosis.

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
Aim: In patients with hepatitis C virus-related liver cirrhosis (LC) who achieve sustained virological responses (SVRs) through treatment with direct-acting antiviral agents (DAAs), it remains unclear whether there are improvements in gastroesophageal varices (GEVs) and portal hypertension. We investigated changes in liver function and GEVs that occurred after DAA therapy. Materials and Methods: We evaluated the medical records of 195 patients with hepatitis C virus-related LC who received DAAs. A total of 171 patients achieved SVRs, among whom 36 had GEVs before or after receiving DAA therapy. The liver function, fibrosis, and GEVs were re-evaluated every 6 months after receiving DAA therapy. The risk factors for progressive GEVs were investigated. Results: DAA therapy resulted in improvements in liver function (indicated by aspartate transaminase, alanine transaminase, and serum albumin levels) and fibrosis (indicated by type IV collagen levels and the Fibrosis-4 index). After receiving DAA therapy, 27 patients had stable GEVs and 9 had progressive GEVs. With respect to GEV grades before DAA therapy, there was a significant difference between patients with stable and progressive GEVs (p = 0.027). Presence of grade-2 GEVs before starting DAA therapy was a risk factor for GEV progression (odds ratio: 5.83; p = 0.04). Patients with grade-2 GEVs had significantly shorter progression-free periods than those with grade < 2 GEVs (p = 0.025). Conclusions: DAA therapy does not ameliorate GEVs. Furthermore, grade-2 GEVs can worsen after DAA therapy. Therefore, patients with GEVs of grades ≥ 2 should undergo endoscopic surveillance after receiving DAAs.
