Effectiveness of Ledipasvir-Sofosbuvir 12 Weeks After Hepatitis C Virus Genotype 1 Infection and the Factors Associated With Sustained Virologic Response: A Retrospective Study.
Article in Cureus, 2024. 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
backgroundThe combination of ledipasvir and sofosbuvir (LDV/SOF) has been licensed to treat genotype 1 hepatitis C virus infection (HCV) with a 12-week regimen. However, there is scant data from Yemen regarding this combination regimen. Here, we investigate sustained virologic responses (SVR) 12 weeks after HCV treatment with LDV/SOF regimens and the factors that contribute to SVR failure. MATERIAL AND
methodA retrospective cross-sectional study was conducted at Althora General Hospital in Ibb, Yemen, from June 1, 2019, to October 31, 2022, on 53 cases with HCV genotype 1 infection who received combined therapy of LDV/SOF and completed treatment for 12 weeks. The clinical characteristics and treatment follow-up were obtained from patient medical records. Factors associated with SVR failure were investigated in univariate analysis with odds ratio (OR) and 95% confidence interval (CI).
resultThe mean age was 50 ± 15.3 years, and most cases were female (n=36, 67.9%). Comorbidities were diabetes, hypertension, and fatty liver, which were represented in 12 (22.6%), nine (17.0%), and eight (15.1%) cases, respectively. A total of 13 (24.5%) patients had compensated liver cirrhosis, while the remaining 40 patients (75.5%) were non-cirrhotic healthy individuals. The baseline viral load (HCV RNA) was more than 800000 IU/mL in 21 patients (39.6%). Early virological response (ERV) was achieved in 51 patients (96.2%). After treatment, 46 of the patients (86.8%) achieved SVR at Week 12, while failure occurred in two patients (3.8%) and relapse occurred in five patients (9.4%). Blood liver enzymes, including alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase, returned to normal, with statistically significant improvements in non-cirrhotic healthy persons than compensated liver cirrhosis individuals (p= 0.006, 0.006, and 0.010; respectively). Factors associated with SVR failure were older age (OR:1.13; 95% CI: 1.03-1.30, p=0.009), presence of liver cirrhosis (OR: 5.48; 95% CI: 1.04-28.98, p=0.031), having diabetes (OR: 6.33; 95% CI: 1.19-37.93, p= 0.019), baseline higher viral load (OR: 2.27; 95% CI: 0.45-12.73, p<0.001), and not achieving EVR (OR:7.63; 95% CI: 3.77- 17.78, p= 0.009).
conclusionIn this study, we found that LDV/SOF regimens are effective against HCV genotype one infection, allowing for the expansion of 12-week treatment for suitable patients in clinical settings. Additionally, older age, liver cirrhosis, diabetes, higher pretreatment viral load, and non-completion of EVR were associated with SVR failure. However, due to the small number of HCV genotype 1 infected individuals in this study, more corporate data is required to get a clear conclusion.
