Progression and risk factors of hallux valgus angle in elite adolescent dancers: a cohort study.
Article in BMC musculoskeletal disorders, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
introductionTo the best of our knowledge, no previous studies have linked the progression of hallux valgus (HV) with plantar pressure distribution. Therefore, this study aimed to determine the progression of HV angle in elite adolescent dancers and evaluate the risk factors associated with foot plantar pressure during demi-pointe movement.
methodsFor this cohort study, 40 adolescent dancesport dancers (age: 14.5 ± 1.3 years; height: 168.3 ± 8.3 cm; weight: 52.4 ± 8.1 kg) were recruited from a dancesport specialty school. All participants reported no foot or lower limb injuries or symptoms in the past year and were not undergoing any rehabilitation or medication treatment. The HV angle was measured by photography (HVAp). The HVAp survey included baseline and follow-up assessments after 1 year. Foot plantar pressures (kPa) were obtained using the F-Scan measurement system (Tekscan, Tokyo, Japan), and the data were divided into two categories based on the foot location (type 1: hallux, toe, and metatarsophalangeal [MTP] joint area and type 2: medial, middle, and lateral areas). Data were analyzed using the Pearson's chi-square test and multiple logistic regression.
resultsThe HVAp measurement demonstrated excellent reliability. A significant increase of 2.1° ± 3.5° in the HV angle of elite adolescent dancers was found at the 1-year follow-up assessment relative to that at baseline. There were significant correlations between the HVAp variation values and the hallux (r = - 0.480, P = 0.002), toe (r = - 0.313, P = 0.049), and MTP joint area (r = 0.446, P = 0.004) plantar pressure percentages in the type 1 category and medial area (r = - 0.331, P = 0.037) and middle area (r = 0.386, P = 0.014) pressure percentages in the type 2 category. Based on the multivariate logistic regression analysis, the HVAp variation values were associated with foot plantar pressure in the hallux (odds ratio [OR]: - 0.12, 95% confidence interval [CI]: - 0.191 to - 0.048, P = 0.002) and middle areas (OR: 0.09, 95% CI: 0.019 - 0.161, and P = 0.014) from the two categories, respectively.
conclusionThis study demonstrated significant progression of the HV angle in elite adolescent dancers over 1 year, which was significantly associated with increased foot plantar pressure in the middle area and decreased plantar pressure in the hallux area. These findings highlight the importance of monitoring and addressing foot plantar pressure in adolescent dancers.
