Observational study in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04704037 (Mobilizing Early Management of Mental Health Complications After Mild Traumatic Brain Injury), which is not on this map. Cited by 1 paper.

1 · What the graph read from it

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.

Abstract

objectiveTo investigate the prognostic value of the Subgroups for Targeted Treatment (STarT) Screening Tool adapted for concussion (STarT-C) on persistent symptoms and disability at 6-9 months following mild traumatic brain injury (mTBI).

designSecondary analysis of two prospective studies: an observational cohort study in New Zealand and usual care control arm of a clinical trial in Canada (ClinicalTrials.gov Registry (NCT04704037)).

settingParticipants in the New Zealand cohort were recruited from concussion clinics (five sites) and those in the Canadian cohort were recruited from emergency departments/urgent care centres (eight sites).

participantsNew Zealand participants (n=93, median age 37 years, 60% women) were assessed at median=6 weeks post-injury (T1) and 6 months later (T2). Canadian participants (n=223, median age 38 years, 56% women) were assessed at median=2 weeks (T1) and 6 months later (T2).

main outcome measuresSymptoms at T2 were assessed using the validated Rivermead Postconcussion Symptoms Questionnaire (RPQ) and disability using the WHO Disability Assessment Schedule 2.0 12-item Interview.

resultsIn linear regression analyses, the STarT-C predicted symptom burden (R

conclusionThe STarT-C-a brief screening tool-predicted persistent symptoms and disability in adults following mTBI. The incremental prognostic value of the STarT-C over the RPQ may be variable, but regardless, the tool may be useful for identifying those at risk of prolonged recovery who may benefit from early psychological intervention.
