Occult HCV infection in liver transplanted patients: frequency and consequences.
Article in Clinical and experimental hepatology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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 of the study: Occult hepatitis C virus (HCV) infection (OCI) is a potential source of relapse after liver transplantation with subsequent graft damage. The aim of the study was to detect OCI in patients with living donor liver transplantation (LDLT) who achieved sustained virological response (SVR) after sofosbuvir-based antiviral treatment, and to detect risk factors associated with the development of OCI as well as to determine the effect of direct acting antiviral (DAA) therapy after liver transplantation. Material and methods: 41 patients with living donor liver transplantation who did not receive DAAs before with recurrent HCV infection who achieved a SVR with sofosbuvir-based therapy for 12-24 weeks were recruited. These patients were tested for OCI by HCV-RNA in peripheral blood mononuclear cells (PBMNCs). Those patients with OCI were followed up every 6 months with alanine aminotransferase (ALT), aspartate aminotransferase (AST), and serum HCV-RNA by PCR for 2 years. Results: 92.7% of treated patients achieved HCV SVR 12 weeks. OCI was detected in 4 patients. After follow-up for 18 months, 3 patients continued to have OCI, but one patient presented with progressive elevation of liver enzymes and developed overt HCV infection with positive HCV-RNA PCR in the serum. This patient was retreated with sofosbuvir 400 mg + ledipasvir 90 mg for 12 weeks with resultant negative HCV-RNA PCR in both serum and PBMNCs in addition to normalization of liver enzymes. Conclusions: Occult HCV infection is a potential source of HCV relapse after liver transplantation which should be investigated for in PBMNCs or liver biopsy.
