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

backgroundThe feeding arteries of fourth ventricular tumors often arise from the posterior inferior cerebellar artery (PICA), particularly the tonsillomedullary and telovelotonsillar segments. Achieving early control of these feeders is critical to minimize bleeding.

methodWe present a surgical technique that facilitates early control of feeders from the telovelotonsillar segment, which courses dorsally to the inferior medullary velum and tela choroidea, by wide and deep opening of the uvulo-tonsillar space before tumor manipulation.

conclusionThis technique enables early interruption of PICA feeders, allowing safe and effective devascularization of fourth ventricular tumors with abundant arterial supply.
