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
purposeConcussion and its sequalae of persistent post-concussion symptoms (PPCS) are significant healthcare burdens in the paediatric population. For affected patients, PPCS significantly impacts their academic performance, social interactions, and quality of life. This study is undertaken to investigate the prevalence of PPCS, identify associated risk factors and outcomes, and evaluate the applicability of the Post-Concussion Symptom Scale (PCSS) in school-going children diagnosed with concussive head injury.
methodsThis is a single-institution, retrospective study conducted from January 2020 to April 2023 (40 months). All patients aged 5 to 18 years diagnosed with concussion at the KK Women's and Children's Hospital, Singapore, are included. Subsequently, they are stratified into 2 groups: non-PPCS (symptom resolution within 4 weeks) and PPCS (symptoms persisting beyond 4 weeks). Data on patient demographics, clinical history, mechanism of head injury, symptomatology, PCSS scores, and recovery times are analyzed. Multivariable logistic regression is performed to identify independent predictors of PPCS.
resultsA total of 220 patients were recruited for this study. Eighty-seven (39.5%) patients had PPCS. Sports-related injuries were the most common cause of concussion. Higher PCSS scores were significantly associated with PPCS (p < 0.01). Independent predictors of PPCS included female gender (p = 0.01), history of psychiatric illness (p < 0.01), and childhood headaches (p = 0.01).
conclusionTo our knowledge, this is the first longitudinal study focused on PPCS in a Southeast Asian paediatric population. Early identification of high-risk patients and clinical predictors is crucial to initiate time-sensitive interventions for optimal outcomes.
