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.

2 · The registry

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

Hepatitis C virus (HCV) can infect naïve cells via entry of "cell-free" extracellular virus or direct "cell-to-cell" transmission. Here, we describe an assay for detecting HCV cell-to-cell transmission, using a non-growing cell culture system that avoids confounding effects of cell growth. The assay consists of infecting a small number of cells in a confluent monolayer and then blocking subsequent cell-free extracellular virions with a neutralizing antibody such that only cell-to-cell transmission may occur. Under these conditions, incubation at 37 °C results in the formation of infected cell foci. The extent of cell-to-cell spread can then be determined by counting the number of cells in each focus. The assay may be modified to assess the effects of inhibitors and/or specific cellular genes on cell-to-cell spread of HCV.
