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

objectiveTo quantify the reproducibility of knee articular cartilage T2 across a wide range of MR systems. MATERIALS AND

methodsThe reproducibility of T2 relaxation time mapping was assessed by measuring the knee of a volunteer (n

resultsLow-to-moderate inter-scanner variation for the knee ROIs, CV = 2.2% to 22.8%, CV DISCUSSION: Reproducibility of quantitative T2 can vary between healthcare facilities and scanners but also between the cartilage compartments. The variation is sufficiently small to consider T2 mapping reproducible. Phantom measurements support this result.
