Concurrent validity of PROMIS metrics with the EOSQ-24 in early onset scoliosis.
Article in Spine deformity, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeTo evaluate the concurrent validity of 3 Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric metrics (Mobility, Pain Interference, and Anxiety) in Early Onset Scoliosis (EOS) by using the 24-item EOS Questionnaire (EOSQ-24) as an anchor.
methodsWe retrospectively reviewed PRO data of children with EOS from April 2021 to June 2023. PROMIS Pain Interference, Mobility, Anxiety, and EOSQ-24 were simultaneously completed. Comparisons were made according to each EOSQ-24 domain with Pearson correlations. Correlations above 0.7 indicate a strong relationship, 0.4 to 0.69 indicate a moderate relationship, and 0.1 to 0.39 indicate a weak relationship.
results236 children (84 boys, 152 girls) ages 10.4 ± 3.5 years (range: 5-19 years) with curves averaging 39° ± 22° were included. The strongest correlations between the 3 PROMIS metrics and each EOSQ-24 domain were between Mobility and EOSQ-24 Physical function (r = 0.75, p < 0.001), Pain Interference and EOSQ-24 Pain/discomfort (r = -0.68, p < 0.001), and Anxiety and EOSQ-24 Emotion (r = -0.51, p < 0.001). The weakest correlations between all 3 PROMIS metrics and each EOSQ-24 domain were for General health (r ≤ 0.35, p < 0.001), Financial impact (r ≤ 0.36, p < 0.001), and Pulmonary function (r ≤ 0.39, p < 0.001).
conclusionThe 3 PROMIS metrics (Mobility, Pain Interference, Anxiety) demonstrate moderate to strong validity with the related EOSQ-24 domains (Physical function, Pain/discomfort, Emotion). The weak associations between EOS-specific concerns demonstrate diverging constructs. This study supports the use of the EOSQ-24 given the adequate associations with the appropriate domains while highlighting the value of other EOSQ domains.
