Incidence, Characteristics, and Risk Factors of Post-Radiosurgery Headaches: A Prospective Observational Study.

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
aimsThis prospective observational study aimed to characterize the incidence, clinical features, and risk factors of headaches following CyberKnife radiosurgery (CKRS) in patients with intracranial pathologies.
methodsIn a prospective observational study conducted from January 2022 to January 2023, we enrolled consecutive patients who underwent CKRS. Patients completed headache-related questionnaires developed based on the International Classification of Headache Disorders (ICHD-3) guidelines at 24 h, 1 week, and 3 months post-radiosurgery. The incidence of CKRS-related headaches was determined, and the link between risk factors and outcomes was analyzed.
resultsOf 153 patients (female 58.2%; mean age 47.7 ± 14.8 years), all completed a 3-month follow-up. Among 153 patients, 61 (39.9%) developed post-CKRS headaches, with 83.6% reporting peak intensity within 2 weeks post-procedure. Fifty (32.7%) developed headaches within 2 weeks, resolving within 3 months. A strong temporal association between headache onset and CKRS supports a causal relationship. Multivariate Cox regression analysis identified female sex (HR = 2.16, 95% CI = 1.14-4.11, p = 0.019), younger age (HR = 0.97 per year, p = 0.006), absence of prior craniocerebral surgery (HR = 0.55, p = 0.046), and multiple lesions (HR = 2.28, p = 0.047) as independent risk factors. Although headaches were more frequently observed following radiation targeting the basal ganglia and thalamus, this association lacked statistical significance (p > 0.05).
conclusionsHeadaches attributed to brain radiosurgery constitute a significant yet overlooked clinical issue, warranting increased focus from surgical teams to deliver improved and tailored treatment.
