Elevated serum neurologic biomarker profiles after cardiac arrest in a porcine model.

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
Introduction: Swine exhibit cerebral cortex mitochondrial dysfunction and neuropathologic injury after hypoxic cardiac arrest treated with hemodynamic-directed CPR (HD-CPR) despite normal Cerebral Performance Category scores. We analyzed the temporal evolution of plasma protein biomarkers of brain injury and inflammatory cytokines, as well as cerebral cortical mitochondrial injury and neuropathology for five days following pediatric asphyxia-associated cardiac arrest treated with HD-CPR. Methods: One-month-old swine underwent asphyxia associated cardiac arrest, 10-20 min of HD-CPR (goal SBP 90 mmHg, coronary perfusion pressure 20 mmHg), and randomization to post-ROSC survival duration (24, 48, 72, 96, 120 h; n = 3 per group) with standardized post-resuscitation care. Plasma neurofilament light chain (NfL), glial fibrillary acidic protein (GFAP), and cytokine levels were collected pre-injury and 1, 6, 24, 48, 72, 96, and 120 h post-ROSC. Cerebral cortical tissue was assessed for: mitochondrial respirometry, mass, and dynamic proteins; oxidative injury; and neuropathology. Results: Relative to pre-arrest baseline (9.4 pg/ml [6.7-12.6]), plasma NfL was increased at all post-ROSC time points. Each sequential NfL measurement through 48 h was greater than the previous value {1 h (12.7 pg/ml [8.4-14.6], p = 0.01), 6 h (30.9 pg/ml [17.7-44.0], p = 0.0004), 24 h (59.4 pg/ml [50.8-96.1], p = 0.0003) and 48 h (85.7 pg/ml [61.9-118.7], p = 0.046)}. Plasma GFAP, inflammatory cytokines or cerebral cortical tissue measurements were not demonstrably different between time points. Conclusions: In a swine model of pediatric cardiac arrest, plasma NfL had an upward trajectory until 48 h post-ROSC after which it remained elevated through five days, suggesting it may be a sensitive marker of neurologic injury following pediatric cardiac arrest.
