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

Cryo-electron tomography (cryoET) allows 3D visualization of cellular structures at molecular resolution in a close-to-native state and therefore has the potential to help elucidate early events of HIV-1 infection in host cells. However, structural details of infecting HIV-1 have not been observed, due to technological challenges in working with rare and dynamic HIV-1 particles in human cells. Here, we report structural analysis of HIV-1 and host-cell interactions by means of a correlative high-speed 3D live-cell-imaging and cryoET method. Using this method, we showed under near-native conditions that intact hyperstable mutant HIV-1 cores are released into the cytoplasm of host cells. We further obtained direct evidence to suggest that a hyperstable mutant capsid, E45A, showed delayed capsid disassembly compared to the wild-type capsid. Together, these results demonstrate the advantages of our correlative live-cell and cryoET approach for imaging dynamic processes, such as viral infection.
