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

Anterior foramen magnum (AFM) meningiomas are difficult to treat because they are situated in anatomically complex regions. One of the most common approaches for AFM meningiomas is the far lateral approach. We describe our exo- and endoscopic two-step approach (EETA) through suboccipital craniotomy. An exoscope is used to remove the tumour's lateral part, whereas an endoscope is used to remove the residual tumour in the exoscope's blind spots, including the brainstem's ventral side. EETA is a viable option for treating AFM meningiomas because it provides an adequate surgical field of view and is minimally invasive.
