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

Vancouver General Hospital has a rich neurosurgical history; however, little is documented of the role the institution played in the history of extracranial to intracranial (EC-IC) bypass as a surgical therapy. A review of the literature on the history of cerebrovascular neurosurgery was performed to augment a comprehensive personal interview provided by Dr Sydney Peerless to provide a new insight into the journey towards our contemporary understanding of bypass surgery. Along this timeline, we outline key historic figures and their contributions, as well as document the first small vessel EC-IC bypass at Vancouver General Hospital in western Canada.
