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

purposeRecently, a new minimally invasive technique called 'vertebral body stenting' (VBS) was introduced for the treatment of osteoporotic vertebral fractures. The technique was developed to prevent the loss of reduction after deflation of the balloon and to reduce the complication rate associated with cement leakage.

methodsThe amount of kyphosis correction, improvement of vertebral body height and quantitative cement leakage rate by applying CT-based quantitative volumetry after VBS were measured in 27 patients (55 vertebra) and compared with a control group (29 patients, 61 vertebrae), which was treated with conventional vertebroplasty.

resultsAfter VBS, a significant improvement was seen in vertebral height, compared to conventional vertebroplasty. The mean improvement in segmental kyphosis and vertebral kyphosis were 5.8° (p < 0.05) and 3.5° (p < 0.05), respectively. In the VBS group, the mean injected volume of cement per vertebral body was 7.33 cm(3) (3.34-10.19 cm(3)). The average amount of cement outside the vertebrae was 0.28 cm(3) (0.01-1.64 cm(3)), which was 1.36% of the applied total cement volume. In the vertebroplasty group, the applied mean volume of the cement per level was 2.7 cm(3) (1-5.8 cm(3)) and the average amount of cement outside the vertebrae was 0.15 cm(3) (0.01-1.8 cm(3)), which was 11.5% (0.2-60%) of the applied total volume of cement.

conclusionThe frequency of cement leakage after VBS was 25.5% compared to 42.1% in the vertebroplasty group. VBS led to a significant decrease in the leakage rate compared with conventional vertebroplasty.
