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
purposeThe Knee Injury Osteoarthritis Outcome Score (KOOS)-Child questionnaire is one of the frequently child-friendly measures used in pediatric studies. The aim of this study was to transculturally adapt the Greek version of KOOS-Child and evaluate its clinimetric properties in children with knee disorders.
methodsChildren visiting the Outpatients Orthopaedic Clinic of a Greek Paediatric General Hospital were considered eligible if they were aged 8-14 years, had a knee soft tissue injury and associated physical limitations. The transcultural adaptation was based on a multistage backward translation approach. Participants completed the KOOS-Child at their first visit to the orthopedic specialist (baseline), 2 weeks and 3 months after baseline. Content validity of the KOOS-Child was evaluated using general QoL measures (KIDSCREEN and Kid-KINDL) and construct validity was explored by correlating relevant items. Responsiveness was evaluated according to the children's response on the given orthopeadic treatment.
resultsSample consisted of 59 children (30 males), aged: 11 ± 1.8 years. The KOOS-Child showed high internal consistency (Cronbach's a: 0.80-0.96). Adequate convergent validity with > 75% relevant a priori hypotheses was confirmed. Construct validity was moderate to strong (Pearson's r correlations between related KOOS and Kid-KINDL subdimensions: 0.54-0.62). KOOS and KIDSCREEN subdimensions correlations were fair (Pearson's r correlations: 0.32-0.65). KOOS-Child's diagnostic accuracy was high. Factor analysis extracted height factors accounting for 76.15% of the total variance, confirmed by the scree plot. Responsiveness was moderate to high with Cohen's d from 0.6 to 1.4.
conclusionThe Greek version of the KOOS-Child demonstrated excellent internal consistency, good construct validity, diagnostic accuracy and interpretability as well as good responsiveness. The measure could be used across Greek children with orthopaedic knee problems. Generalisability of findings is limited due to the relatively limited cohort. LEVEL OF EVIDENCE: II.
