1 · What the graph read from it

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.

Abstract

Hepatitis C continues to be a significant public health problem despite advancements in antiviral therapeutics. To eliminate this disease, an effective vaccine against new infections and re-infections is needed. However, to date only one Hepatitis C virus (HCV) envelope protein (E1E2) immunogen, developed by Chiron Inc., has been tested in a Phase I clinical trial (ClinicalTrials.gov identifier NCT00500747). To establish a benchmark for elicitation of broadly neutralizing antibodies (bnAbs) by E1E2, we previously immunized non-human primates (NHPs) with this immunogen and isolated monoclonal nAbs that exhibit neutralization potency comparable to human nAbs. Here we show that NHP nAbs, encoded by germline genes IGHV1-138*01 and IGHV4-NL_5*01 (homologs of human IGHV1-69*10 and IGHV4-59*12, respectively), recognize a relatively conserved E2 region (neutralizing face) proximal to antigenic region 3 (AR3). These NHP AR3-targeting nAbs share highly similar binding modes to human AR3-targeting nAbs, suggesting a similarity in human and NHP immune responses to the same HCV immunogen.
