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

The precision and quality of a radiosurgical procedure depend on the ability to immobilize and position the patient's head. Often, this is accomplished by means of a mechanical headframe. The ability to accurately position the head and keep it in place during the procedure depends directly on the rigidity of the headframe. This characteristic of the Leksell headframe (Elekta, Atlanta, GA, US) was evaluated by determining the impact of typical forces encountered in clinical practice on its rigidity. A quantitative analysis of the individual forces was then used to draw conclusions on the impact of the headframe's ability to accurately position the target at the desired treatment position. This article is designed to provide guidance to the user of mechanical headframes and quantitate the positioning accuracy of this frame.
