Do Initial Symptom Factor Scores Predict Subsequent Impairment Following Concussion?
Article in Clinical journal of sport medicine : official journal of the Canadian Academy of Sport Medicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectiveSymptom factors present during the first week following concussion may predict subsequent concussion outcomes and recovery duration. We hypothesized that a high loading on cognitive-fatigue-migraine and somatic factors would be predictive of neurocognitive impairment following concussion. We also hypothesized that the affective factor would be related to vestibular symptoms and impairment.
designProspective repeated measures.
settingConcussion specialty clinic.
participantsAthletes aged 13 to 20 years diagnosed with a concussion within the past 7 days. INDEPENDENT VARIABLE: Symptom factors at the initial visit 1 to 7 days after injury.
main outcome measureSymptom factor score, neurocognitive testing, and vestibular/ocular motor assessment at the second visit (2-4 weeks after injury).
resultsThe somatic symptom factor from the initial visit was significant (P < 0.05) in all vestibular/ocular screening components (P < 0.05) but not neurocognitive test performance (P > 0.05) at the second visit. The cognitive-migraine-fatigue and affective symptom factors predicted symptom burden at the second visit (P < 0.001) but did not predict recovery time (P = 0.200).
conclusionsThe somatic symptom factor during the first week after injury predicted symptom provocation during vestibular/ocular screening at 2 to 4 weeks after injury. Specifically, higher scores on somatic symptom factor at the initial visit predicted worse symptom reporting for all vestibular/ocular screening components at the second visit. Patients with higher scores on the cognitive-migraine-fatigue and affective symptom factors at the initial visit predicted total symptom burden at the second visit.
