1 · What the graph read from it

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.

2 · The registry

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

This study investigated the impact of post-traumatic kyphosis (PTK) on the lumbar spine using a local Cobb angle of 30° as the cutoff point. The measurements included the local Cobb angle, lumbar lordosis angle (L1-L5), intervertebral space angle (IVSA), lumbar disc degeneration, and posterior wall height loss (PWHL). Patient characteristics such as sex, age, disease duration, American Spinal Injury Association (ASIA) grade, fracture site, bone mineral density (BMD), Oswestry Disability Index (ODI), and visual analogue scale (VAS) score were also recorded. Patients were divided into two groups based on the thoracolumbar local Cobb angle: Group 1 (local Cobb angle > 30°, n = 48) and Group 2 (local Cobb angle ≤ 30°, n = 28). Comparative analysis revealed that Group 1 had a significantly longer disease duration, higher VAS and ODI scores, greater lumbar lordosis angle, increased L4/5 IVSA, and more severe lumbar disc degeneration (p < 0.05). Furthermore, across all patients, disease duration, lumbar lordosis angle, and L4/5 IVSA were positively correlated with the local Cobb angle (p < 0.05). These findings suggest that when the local Cobb angle exceeds 30°, PTK may aggravate lumbar degeneration.
