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

objectivesTo evaluate the diagnostic performance of diffusion-weighted imaging (DWI) as a single non-invasive method in detecting prostate cancer (PCa) and to deduce its clinical utility.

methodsA systematic literature search was performed to identify relevant original studies. Quality of included studies was assessed by QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies). Data were extracted to calculate sensitivity and specificity as well as running the test of heterogeneity and threshold effect. The summary receiver operating characteristic (SROC) curve was drawn and area under SROC curve (AUC) served as a determination of the diagnostic performance of DWI for the detection of PCa.

resultsA total of 21 studies were included, with 27 subsets of data available for analysis. The pooled sensitivity and specificity with corresponding 95% confidence interval (CI) were 0.62 (95% CI 0.61-0.64) and 0.90 (95% CI 0.89-0.90), respectively. Pooled positive likelihood ratio and negative likelihood ratio were 5.83 (95% CI 4.61-7.37) and 0.30 (95% CI 0.23-0.39), respectively. The AUC was 0.8991. Significant heterogeneity was observed. There was no notable publication bias.

conclusionsDWI is an informative MRI modality in detecting PCa and shows moderately high diagnostic accuracy. General clinical application was limited because of the absence of standardized DW-MRI techniques. KEY POINTS: • DWI provides incremental information for the detection and evaluation of PCa • DWI has moderately high diagnostic accuracy in detecting PCa • Patient condition, imaging protocols and study design positively influence diagnostic performance • General clinical application requires optimization of image acquisition and interpretation.
