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

purposeTo determine whether needle-tip artifact can be reduced by replacing stainless steel stylets with lower atomic number materials. MATERIALS AND

methodsA soft tissue phantom and deceased porcine model (kidney, liver, and lung) were used to analyze computed tomography (CT) beam-hardening artifact with different stylet materials. Carbon fiber, aluminum, titanium, nitinol, stainless steel, copper, brass, and molybdenum were used in the phantom, and aluminum and stainless steel in the porcine model. CT scans of the phantom (120 kV, 15 mA or 140 kV, 10 mA) and porcine model (120 kV, 30 mA) were obtained with each stylet. Images were analyzed for artifact length, artifact width, needle width, and artifact intensity and ranked to determine the impact of artifact on image quality in the porcine model.

resultsIn the soft tissue phantom, artifact intensity worsened with increasing Z-number (P = .001 for 120 kV, 15 mA; P < .001 for 140 kV, 10 mA). In the porcine model, the aluminum stylet (Z = 13) had less artifact length and width and greater Hounsfield units, resulting in a less intense artifact, compared with stainless steel (Z = 26) in all measurements in the kidney, liver, and lung (P < .05), except for artifact width and length in the lung and needle width in the kidney (P > .05). Blinded readers ranked the artifact from stainless steel stylet as significantly worse than aluminum (P < .005, kappa = 0.63).

conclusionsLower-Z-number stylet materials substantially decreased metal artifact emanating from needle tips.
