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 determine the comparative diagnostic performance of standard-b-value (≥500 mm(2)) vs low-b-value (<500s mm(-2)) diffusion-weighted imaging (DWI) for discriminating malignant from benign vertebral compression fractures.

methods12 studies with a total of 350 malignant and 312 benign vertebral fractures were included.

resultsThe apparent diffusion coefficient (ADC) value of benign vertebral compression fractures was lower than that of malignant vertebral compression fractures (SMD = 1.81, 95% CI 0.98 to 2.64 Z = 4.27, p < 0.05). ADC value difference was more pronounced in the group of low-b-value DWI (SMD = 2.31, 95% CI 1.02 to 3.60 Z = 3.51, p < 0.05) than in the group of standard-b-value DWI (SMD = 1.38, 95% CI 0.18 to 2.59 Z = 2.25, p < 0.05). Ethnicity stratified analysis demonstrated higher ADC values in benign vertebral compression fractures in comparison to malignant tissues in both the Asian and Caucasian subgroups (Asians: SMD = 2.400, 95%CI 1.45 to approximately 3.35, p<0.05; Caucasians: SMD = 0.592, 95 % CI -0.848 to approximately 2.032, p < 0.05). And the ADC value difference was more pronounced in the Asian subgroup.

conclusionADC value appears to be a reliable method to differentiate benign from malignant fractures. Low-b-value DWI was more a valuable parameter than standard-b-value DWI for discriminating malignant from benign vertebral compression fractures. And the diffusion characteristics of the benign vertebral fractures such as osteoporosis, trauma and infection have rarely been investigated separately. ADVANCES IN KNOWLEDGE: The use of low-b-value DWI for differentiation of benign and malignant vertebral fractures is recommended.
