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

purposePercutaneous vertebroplasty (PVP) is a common procedure in spine surgery. Bone cement leakage is the most common complication related to this procedure. The purpose of this study was to assess the incidence and risk factors for cement leakage after PVP.

methodsA total of 485 patients who underwent PVP between August 2003 and August 2013 were enrolled in the study. Clinical and radiological characteristics, including age, gender, diagnosis, operated level, surgical approach, type of anesthesia, volume of bone cement, fracture type, and fracture severity, were considered as potential risk factors. Cement leakage was assessed based on post-operative imaging examination. Six types of leakage were defined and risk factors for each type were analyzed.

resultsThe incidence of leakage was 58.2 %. Binary logistic analysis revealed that larger volume of bone cement (P < 0.001) and higher fracture severity grade (P < 0.001) were the strongest independent risk factors. Univariate analysis and multinomial logistic analysis showed that surgical approach (P < 0.001), gender (P = 0.016), and operated level (P = 0.032) were additional risk factors for leakage. Further analysis showed that more bone cement was used in bilateral than unilateral approaches, that men had larger volumes of bone cement injected than women, and that more bone cement was injected into lumbar vertebrae than thoracic vertebrae. Therefore, these risk factors (surgical approach, gender, and operated level) could be attributed to excess bone cement usage.

conclusionsCement leakage is very common with PVP. Higher fracture severity grade and larger volume of bone cement were the two strongest independent risk factors for leakage.
