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

Background and purpose: Cancer patients are at increased risk of impaired bone health. The aim of this study was to develop a method for estimating bone mineral density (BMD) from computed tomography (CT) images acquired for radiotherapy (RT) planning. Materials and methods: We calculated BMD (mg/cm Results: The derived translation function (BMD = 0.7161 × CT number - 1.212; R = 0.99) agreed in the patient data set with the spine phantom calibration (mean difference 8.7 mg/cm Conclusions: A method for reliable BMD assessment from RT CT images was successfully developed and validated. Future studies should establish clinically relevant BMD cut-off values.
