Prognostic Value of Circadian Brain Temperature Rhythm in Basal Ganglia Hemorrhage After Surgery.
Article in Neurology and therapy, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
introductionIntracerebral hemorrhage (ICH) is associated with high mortality and morbidity rates. However, both the rhythmic variation and prognostic value of brain temperature after ICH remain unknown. In this study, we investigated brain temperature rhythm and its prognostic value for post-operative mortality and long-term functional outcomes in patients with ICH.
methodsPost-operative diurnal brain temperature patterns at the basal ganglion are described. Following surgery for ICH, 78 patients were enrolled, and intracranial pressure and brain temperature were monitored using a fiber optic device. Brain temperature mesor, amplitude, and acrophase were estimated from the recorded temperature measurements, using cosinor analysis, and the association between these patterns and clinical parameters, mortality, and functional outcomes at the 12-month follow-up were examined.
resultsAccording to cosinor analysis, brain temperature in 55.1% of patients showed a circadian rhythm within 72 h post-surgery. The rhythm-adjusted mesor of brain temperature (± standard deviation) was 37.6 (± 0.7) °C, with a diminished mean amplitude. A temperature acrophase shift was also observed. Multivariate logistic regression analysis revealed that initial age and circadian rhythm of brain temperature appeared to be predictive and prognostic of functional outcomes. Further, patients with higher brain temperature mesor were more likely to survive than those with a lower mesor.
conclusionFor patients with ICH, brain temperature rhythm analysis is an improved prognostic tool for mortality and functional outcome predictions.
