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

Scanning transmission electron microscopic (STEM) tomography of high-pressure frozen, freeze-substituted semi-thin sections is one of multiple approaches for three-dimensional recording and visualization of electron microscopic samples. Compared to regular TEM tomography thicker sample sections can be investigated since chromatic aberration due to inelastic scattering is not a limit. The method is ideal to investigate subcellular compartments or organelles such as synapses, mitochondria, or microtubule arrangements. STEM tomography fills the gap between single-particle electron cryo-tomography, and methods that allow investigations of large volumes, such as serial block-face SEM and FIB-SEM. In this article, we discuss technical challenges of the approach and show some applications in cell biology. It is ideal to use a 300-kV electron microscope with a very small convergence angle of the primary beam ("parallel" beam). These instruments are expensive and tomography is rather time consuming, and therefore, access to such a high-end microscope might be difficult. In this article, we demonstrate examples of successful STEM tomography in biology using a more standard 200-kV microscope equipped with a field emission tip.
