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

The Crankshaft Phenomenon (CSP) is a significant complication that can occur after posterior spinal fusion, particularly in growing patients with scoliosis. It results from continued anterior spinal growth while the posterior column remains fused, leading to progressive spinal deformities such as loss of correction, increased vertebral rotation, and rib prominence. This phenomenon has been predominantly observed in pediatric patients with idiopathic, congenital, and neuromuscular scoliosis. Although clinical symptoms may be subtle, radiographic signs are crucial for diagnosis but can be challenging to evaluate due to postoperative changes and instrumentation. Current treatment options are limited, often requiring revision surgeries in cases of progressive deformities. This review aims to provide a comprehensive overview of the current understanding of CSP, including its pathophysiology, diagnostic challenges, risk factors, prevention strategies, and potential treatments.
