The long-term course and relationship with survival of multidimensional fatigue in patients with brain metastases after Gamma Knife radiosurgery.
Trial report in Journal of cancer research and clinical oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02953756 (Cognitive Outcome After Gamma Knife Radiosurgery in Patients With 1-10 Brain Metastases), which is not on this 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.

Abstract
purposeThe aims of this study were to evaluate long-term multidimensional fatigue in patients with brain metastases (BM) up to 21 months after Gamma Knife radiosurgery (GKRS) and (change in) fatigue as predictor of survival.
methodsPatients with 1 to 10 BM, expected survival > 3 months, and Karnofsky Performance Status ≥ 70, and Dutch non-cancer controls were included. Fatigue was measured with the Multidimensional Fatigue Inventory. Levels of fatigue between patients and controls were compared using independent-samples t-tests. Linear mixed models were used to evaluate fatigue within the patient group up to 21 months after GKRS. Pre-GKRS fatigue and minimal clinically important (MCI) changes in fatigue in the first three months (defined as a 2-point difference) after GKRS were evaluated as predictors of survival time.
resultsPrior to GKRS, patients with BM (n = 92) experienced significantly higher fatigue on all subscales than controls (n = 104). Over 21 months, physical fatigue increased, and mental fatigue decreased significantly. More specifically, general, and physical fatigue increased significantly between pre-GKRS and 3 months, followed by stable scores between 3 (n = 67) and 6 (n = 53), 6 and 12 (n = 34) and 12 and 21 (n = 21) months. An MCI increase in general or physical fatigue over the first 3 months after GKRS was a significant predictor of shorter survival time.
conclusionExcept for mental fatigue, all aspects of fatigue remained elevated or further increased up to 21 months after treatment. Furthermore, an increase in general or physical fatigue within three months after GKRS may be a prognostic indicator for poorer survival.
