A cervical lordosis curvature decline in Chinese asymptomatic populations from 2016 to 2024: a comparative analysis.
Article in BMC musculoskeletal disorders, 2026. 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
backgroundThere is increasing concern regarding the effects of contemporary lifestyles on spinal health. This study aimed to evaluate recent trends in cervical lordosis (CL) curvature over the past eight years.
methodsAsymptomatic individuals who underwent cervical spine radiography at four hospitals were randomly selected from hospital databases for a comparative analysis of data spanning from 2016 to 2024. The curvature of CL was assessed using three methods: the C2-C7 Cobb angle (Cobb A), the C2-C7 Harrison posterior tangent angle (Harrison A), and Borden’s method for evaluating CL depth. Measurements of CL curvature were performed using the previously described methodologies by two authors, employing a Picture Archiving and Communication System. The selected participants were categorized into two cohorts: young adults (aged < 40 years) and older adults (aged ≥ 40 years).
resultsIn the 2016 and 2024 cohorts, no significant age differences based on gender were observed. Females in these cohorts exhibited significantly lower CL curvature measurements, as assessed by the Cobb A and CL depth indices, in comparison to their male counterparts. Furthermore, within these cohorts, older adults demonstrated a reduction in CL depth compared to younger adults. The assessment of CL curvature in the 2024 cohort, utilizing the Cobb A and Harrison A methods, revealed a reduction in measurements compared to the 2016 cohort. This decrease was observed across both genders and all age groups.
conclusionsThe findings of this study indicate a decline in CL curvature over the past eight years. Further investigation is warranted to understand the etiology and clinical significance of this observed trend.
