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

Electron tomography (ET) has emerged as a critical tool for visualizing the three-dimensional ultrastructure of biological specimens at nanometer resolution. This chapter focuses on the application of ET in studying synaptic ultrastructure, in particular postsynaptic density, providing a detailed overview of the techniques and methodologies used to achieve high-resolution three-dimensional reconstruction of synapses. Beginning with an introduction to electron tomography, this chapter delves into the principles of electron tomography, including sample preparation, data collection, and image processing. Special emphasis is placed on the application of cryogenic electron tomography, which allows for the visualization of biological samples in their near-native state. This chapter also reviews the historical context of postsynaptic ultrastructure studies using conventional electron microscopy and explores the significant insights gained using electron tomography, particularly in understanding the nanoscale organization and structural complexity of excitatory synapses. This chapter concludes by discussing the future potential of electron tomography in advancing our knowledge of synaptic biology and its implications for neuroscience.
