A cross-sectional study of carnitine deficiency and fatigue in pediatric cancer patients.
Article in Child's nervous system : ChNS : official journal of the International Society for Pediatric Neurosurgery, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposeCarnitine deficiency has been found in cancer patients and has been associated with fatigue. This study aimed to explore the prevalence of carnitine deficiency in pediatric cancer patients and its relationship with fatigue and other potential contributing factors.
methodsChildren with cancer or Langerhans cell histiocytosis who were receiving treatment or had completed therapy were eligible. Patients completed the Pediatric Functional Assessment of Chronic Illness-Fatigue, the Pediatric Quality of Life Inventory Multidimensional Fatigue Scale, a numeric fatigue rating, and had carnitine levels obtained. Carnitine deficiency was defined as a total and/or free carnitine level less than normal for age or an acylcarnitine value higher than normal for age.
resultsData from 142 children aged 8-17 were analyzed. Twenty-eight of 142 (19.7 %) had decreased total and 42.8 % (12/28) had decreased free carnitine levels. No patients had elevated acylcarnitine levels or elevated ratios. Patients with versus without carnitine deficiency differed by age (p = 0.043), treatment (p = 0.037), duration since last chemotherapy (p = 0.020), and body mass index (p = 0.010), but not fatigue, when all data were analyzed together. Yet, a negative relationship between fatigue and carnitine levels was found on a subgroup (off-therapy; fatigue worse than the norm).
conclusionNo significant association between fatigue and carnitine level was demonstrated when data from all patients were analyzed together; however, a significant yet unexpected relationship was found for patients who completed therapy and reported elevated fatigue. Given the small sample size, these results should be interpreted with caution. Future studies to explore impact upon excessive carnitine levels are warranted.
