Sample Preparation for Cryo-Electron Tomography of Influenza A Virus and Infected Cells.

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.
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
Influenza A virus (IAV) replication within host cells relies on tightly controlled, dynamic interactions between viral and cellular components. Yet we have a limited understanding of the viral replication cycle at molecular resolution. Electron microscopy of resin-embedded samples has traditionally been employed to investigate viral replication in cells. However, this technique relies on chemical fixation of samples, dehydration, and resin embedding, which leads to loss of molecular details. Cryo-electron tomography emerged as an indispensable tool enabling the exploration of viral replication within vitrified samples, providing an unperturbed environment. Here, we provide a sample preparation protocol for in vitro and cellular cryo-electron tomography of isolated IAV, as well as for cryo-focused ion beam milling of IAV-infected cells at different stages of infection. The emphasis of this chapter is on infection conditions, grid handling, and adaptation of microscopy settings to the individual sample while adhering to biosafety regulations.
