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

Photoemission electron microscopy (PEEM) offers a potential third modality for large-volume connectomics alongside transmission electron microscopy (TEM) and scanning electron microscopy (SEM). We image osmium stained, ultrathin brain sections on gold coated silicon at synaptic resolution using commercial PEEMs. At coarser resolution, we demonstrate that ultraviolet laser illumination enables gigavoxel-per-second acquisition rates without thermal damage. PEEM combines TEM-like parallel detection with SEM-compatible solid supports into a potentially scalable and cost-effective approach for large-volume connectomes.
