[The association between intelligence and pain in children and adolescents with severely impairing chronic pain : A retrospective analysis].

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
backgroundTo date only few studies have addressed the level of intelligence of children and adolescents with chronic pain. The few currently available studies suggest a cognitive performance of pediatric pain patients in the average range (IQ 85-115); however, only little is known about the relationship between pain characteristics and cognitive skills.
objectiveThe aim of the study was to retrospectively examine the intelligence scores of severely impaired pediatric chronic pain patients to improve the knowledge about the association of pain and cognitive performance and to create a basis for further prospective studies. MATERIAL AND
methodsIn the exploratory evaluation data from N = 180 children and adolescents who were treated as inpatients at the German Pediatric Pain Center in Datteln in 2016 were included. Due to the standardization of the IQ scores a comparison within the sample was possible as well as a comparison to the norm sample.
resultsThe intelligence level of severely impaired pediatric pain patients fell within the normal range (M = 99.32; SD = 14.13). Neither the main pain location nor the emotional variables or pain parameters (e.g. pain intensity) had a significant association with the IQ scores. Compared to the norm sample, pediatric pain patients had a higher processing speed. Intraindividual comparisons showed a significantly lower verbal IQ than performance IQ and a lower verbal comprehension compared to perceptual organization and processing speed. Moreover, there was a negative association between pain intensity, the verbal IQ and verbal comprehension.
conclusionThe results support the assumption that the intellectual performance of pediatric pain patients lies within the average range; however, the results indicate a limited competence in verbal abstraction and expressiveness of pediatric pain patients, which are negatively related to pain intensity. Further studies to examine causal relationships are needed.
