Novel application of near-infrared spectroscopy in detecting iatrogenic vasospasm during interventional neuroradiological procedures.
Article in Brain circulation. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
One of the complications of carotid artery stenting (CAS) is iatrogenic vasospasm caused by mechanical irritation of the blood vessel lumen by a guidewire, catheter, stent retriever, or distal protection devices. Although often self-limiting, the mechanical vasospasm can cause reduction in the cerebral blood flow and result in catastrophic ischemia, especially when undetected and persistent. Real-time cerebral oximetry with near-infrared spectroscopy (NIRS) could detect episodes of cerebral hypoxemia due to vasospasm and facilitate intervention for prevention of hypoxic brain injury during neuro-intervention procedures such as CAS. We present a case scenario where NIRS detected iatrogenic vasospasm even before the conventional tests could identify the event during CAS.
