Radiological anatomical measurements of the superficial temporal artery: an interobserver reproducibility study.

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.
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
purposeNumerous studies have already reported on the anatomy of the superficial temporal artery (STA) on dissection or imaging, and more specifically on CT angiography. However, few studies have reported on the possible variations that exist between readers in the assessment of certain anatomical parameters. The aim of this study was to investigate the reproducibility of different anatomical measurements of the superficial temporal artery with CT angiography.
methodsForty cranial iodine contrast-enhanced CT scans were searched in a retrospective monocentric study. Various anatomical categorical and quantitative measurements (more or less automatic) of the superficial temporal artery were assessed. To evaluate the inter-observer reproducibility of various anatomical measurements of the superficial temporal artery obtained through CT angiography, descriptive statistics, kappa statistics and intraclass correlation coefficients (ICC) were employed.
resultsEighty STAs were analyzed independently by two readers. The kappa coefficient for determining the mode of STA termination was substantial (kappa = 0.782). The number of loops was mean 0.22 vs. 0.25 (p = 0.981; ICC = 0.701) and the number of kinks was mean 5.68vs5.64 (p = 0.876; ICC = 0.860). No significant difference was found between readers for the determination of the distance of the STA termination to different superficial landmark lines. No significant difference in the orientation angles of the STA and the frontal and parietal branches was found. Semi-automatic measurements of the length of the STA appeared (ICC > 0.7) reproducible whereas semi-automatic measurements (surface, perimeter, short diameter, large diameter) appeared statistically less reproducible (ICC < 0.5). These results must also be interpreted in the light of the spatial resolutions inherent in the CT angiography technique.
conclusionThe present study provides information concerning the reproducibility of certain anatomical measurements of the superficial temporal artery in CT angiography.
