Impact of hepatitis C virus genotype on the efficacy of the direct-acting antivirals in chronic kidney disease patients in West Bengal, India.

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
backgroundHepatitis C virus (HCV) infection increases the risk of mortality and morbidity among chronic kidney disease (CKD) patients. However, the advancement of HCV treatment has made this viral infection curable. Thus, the main objective of this study was to comprehend the HCV genotype (GT) distribution and the efficacy of direct-acting antivirals (DAAs) among CKD patients in West Bengal.
methodsOver five years (January 2017 to December 2021), 310 HCV sero-reactive patients were enrolled in this observational prospective study. HCV RNA was quantified using qRT-PCR. The partial amplification of the core (405 bp) and NS5B (389 bp) region was performed by nested RT-PCR followed by Sanger sequencing for HCV genotype analysis using the NCBI genotyping tool. The phylogenetic tree was constructed using the MEGA-X tool.
resultsThe occurrence of HCV RNA positivity was 50.64% (n = 157), and of these 157 patients, 141 (89.81%) completed the DAAs treatment. The most important observation of the study was the prevalence of uncommon HCV genotype GT-1c (67.52%) followed by 1a, 4a, 3a, 1b, and 3b among CKD patients. The overall DAAs efficacy between January 2017 and December 2018 was ~ 97%, and in January 2019 and December 2021, ~ 95% among CKD patients. At the same time, in these two phases, DAAs efficacy among GT-1c-infected CKD patients was ˜ 96% and ˜ 93%, respectively.
conclusionsThe prevalence of GT-1c among CKD patients was unusual in this geographic region. The overall efficacy of DAAs among the CKD population was encouraging. However, the downtrend of the DAAs efficacy in GT-1c may increase concern among this high-risk group in the future. CLINICAL TRIAL: Not applicable.
