Relationship between pin type and depth of skull penetration during frame placement for Gamma Knife radiosurgery.
Article in Journal of radiosurgery and SBRT, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeOur retrospective study addresses the largely unknown effect of fixation pin type on depth of skull penetration during Gamma Knife frame placement.
methodsAbsolute and relative depths were compared for 404 pins of aluminum and titanium in 101 patients who underwent Gamma Knife frame placement at 0.4 Nm (3.5 lb-in) torque.
resultsEffect of pin type was significant: penetration was less in aluminum than titanium pins, for absolute (0.27 mm vs. 0.83 mm) and relative (5.16% vs. 15.53%) depths (p < 0.001 each). Fifty percent of aluminum pins did not measurably penetrate the outer table of the skull whereas 95% of titanium pins penetrated into cancellous bone.
conclusionsAlthough these pin penetration differences did not have a clear clinical correlate, we now recommend titanium pins for their consistent, deeper penetration, which may result in greater frame stability favorable for most clinical applications. Future studies may define optimal torque for aluminum pins.
