Active and resolved HCV infections among people with new HIV-1 diagnoses in Germany, 2009-2019.

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
backgroundHIV and HCV share similar routes of infection. Individuals carrying both viruses experience a faster progression of the liver disease. We have analyzed people with new HIV-1 diagnoses in Germany for active or resolved HCV infection for over ten years. The time period covers the introduction of direct acting antivirals (DAA), a paradigmatic shift in HCV therapy.
methodsA central component of the HIV surveillance in Germany is the notification of new diagnoses. Residual blood samples from 16,539 people with new HIV-1 diagnoses reported between 2009 and 2019 were examined for HCV antigen and/or antibodies. Reactive cases were further investigated for active or resolved HCV infection by RT-qPCR. The results were analyzed with socio-demographic information from the notification forms.
resultsThe study includes samples from 48.0% of all notified HIV-1 diagnoses. The seroprevalence of cases with HCV antigen, antibodies or both, representing active and resolved infections was 6.2% with stable seroprevalence. The average proportion of resolved infections among those was 33.0% with a significant increase since the introduction of DAAs in 2012 (p
conclusionsThe proportion of resolved HCV infections among people newly diagnosed with HIV-1 increased after the introduction of DAAs in Germany. The high prevalence and the low proportion of resolved HCV infections reveal that unmet diagnostic and therapeutic needs exist among PWIDs. The higher proportion of active and resolved cases among individuals of non-German origin particularly requires greater public health attention.
