1 · What the graph read from it

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.

2 · The registry

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

Anti-rods and rings (anti-RR) antibody induction is related to the combination of interferon and ribavirin in the treatment of hepatitis C virus (HCV) infection. If the main factor leading to this autoimmune reaction is the combination of these drugs, is not well known, but in vitro studies shows that ribavirin alone can induce rods and rings structures. New direct-acting antivirals (DAAs) permit HCV treatment without needing interferon but may be associated with ribavirin in the most difficult-to-treat patients. The aim of this study is to evaluate the occurrence of anti-RR in patients with chronic HCV infection, before and after 12 weeks of treatment with DAAs, with and without ribavirin. From Jun 2016 to Oct 2017, 52 HCV-infected patients were screened for anti-RR before and after DAA therapy, including sofosbuvir, daclatasvir, simeprevir, and ribavirin. Serum samples were analyzed using indirect immunofluorescence. The anti-RR was present in 11 (21%) of the 52 patients (51.9% male and mean age of 59.1 years) before using DAAs. All of them had been previously treated and previous exposed to interferon/ribavirin, with exposure time to ribavirin associated with the presence of anti-RR. After 12 weeks of DAA treatment, 3 patients (5.7%) developed the antibody in low titers, and two of them (66%) were interferon/ribavirin experienced. Only one of the 29 naïve patients (3.44%) developed anti-RR during the current treatment. Anti-RR was present in patients previously treated with interferon/ribavirin and can emerge after DAA treatment probably at a lower frequency than after interferon/ribavirin treatment.
