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

backgroundVarious methods have been employed to reduce radiation dose and improve image quality in head computed tomography (CT); however, the impact of different head tilt angles on these factors remains underexplored.

objectiveTo investigate the effects of different head tilt angles on radiation dose and image quality in head CT. MATERIALS AND

methodsA pediatric anthropomorphic head phantom was scanned using dual-source CT at 18 different tilt angles, repeated 10 times at each angle. Image quality was assessed using mean CT (CT

resultsCTDI

conclusionThe findings indicated that adjusting the head tilt angle within the range of -10° to 0° reduced both the head and eye scan lengths as well as the radiation dose, while preserving relatively stable image quality.
