Point-of-care hepatitis C reflex testing and treatment referral in methadone clinic settings in Hong Kong-a pilot study.
Article in IJID regions, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objectives: People who inject drugs (PWID) constitute a population group with a high hepatitis C virus (HCV) burden. With the objectives of assessing the HCV prevalence in PWID and determining the proportion requiring treatment who could be linked to care, this study piloted onsite reflex HCV testing at low threshold methadone clinics, with prompt referral of HCV RNA-positive participants for treatment. Methods: This was a prospective study on methadone clinic attendees in Hong Kong. Questionnaires were completed, finger-prick anti-HCV rapid testing was performed, and positive blood samples were collected for laboratory HCV RNA testing. The proportions of participants along the cascade of HCV care were calculated. Results: In 2021-2022, after 14 evening screening sessions at three methadone clinics, 86 of 354 regular attendees (24%) were recruited. The anti-HCV prevalence was 63% (54/86, 95% confidence interval 52-73%), with 78% (42/54) testing positive for HCV RNA and 79% (33/42) successfully referred. Almost all (31/33) referred participants received direct-acting antiviral (DAA) treatment, 94% (29/31) with full treatment compliance; 55% (16/29) of these compliant participants achieved a sustained virological response, while the remainder had not received post-treatment testing. Conclusions: The use of a simplified testing algorithm in the setting of substitution treatment services, incorporating reflex HCV testing, could be an effective strategy for contributing towards the micro-elimination of HCV in PWID.
