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

Vesicular stomatitis virus (VSV) is an animal virus that based on electron microscopy and its dependence on acidic cellular compartments for infection is thought to enter its host cells in a clathrin-dependent manner. The exact cellular mechanism, however, is largely unknown. In this study, we characterized the entry kinetics of VSV and elucidated viral requirements for host cell factors during infection in HeLa cells. We found that endocytosis of VSV was a fast process with a half time of 2.5 to 3 min and that acid activation occurred within 1 to 2 min after internalization in early endosomes. The majority of viral particles were endocytosed in a clathrin-based, dynamin-2-dependent manner. Although associated with some of the surface-bound viruses, the classical adaptor protein complex AP-2 was not required for infection. Time-lapse microscopy revealed that the virus either entered preformed clathrin-coated pits or induced de novo formation of pits. Dynamin-2 was recruited to plasma membrane-confined virus particles. Thus, VSV can induce productive internalization by exploiting a specific combination of the clathrin-associated proteins and cellular functions.
