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

The parechoviruses differ in many biological properties from other picornaviruses, and their replication strategy is largely unknown. In order to identify the viral RNA replication complex in human parechovirus type 1 (HPEV-1)-infected cells, we located viral protein and RNA in correlation to virus-induced membrane alterations. Structural changes in the infected cells included a disintegrated Golgi apparatus and disorganized, dilated endoplasmic reticulum (ER) which had lost its ribosomes. Viral plus-strand RNA, located by electron microscopic (EM) in situ hybridization, and the viral protein 2C, located by EM immunocytochemistry were found on clusters of small vesicles. Nascent viral RNA, visualized by 5-bromo-UTP incorporation, localized to compartments which were immunocytochemically found to contain the viral protein 2C and the trans-Golgi marker 1,4-galactosyltransferase. Protein 2C was immunodetected additionally on altered ER membranes which displayed a complex network-like structure devoid of cytoskeletal elements and with no apparent involvement in viral RNA replication. This protein also exhibited membrane binding properties in an in vitro assay. Our data suggest that the HPEV-1 replication complex is built up from vesicles carrying a Golgi marker and forming a structure different from that of replication complexes induced by other picornaviruses.
