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

backgroundAdult spinal deformity (ASD) is a disorder characterized by abnormal curvature of the spine resulting from progressive degeneration of spinal elements. Although operative intervention for ASD is commonplace, it is associated with several complications, including proximal junctional kyphosis (PJK) and proximal junctional failure (PJF). The objective of this review is to outline the role of proximal fixation in preventing PJK and PJF.

methodsWe conducted a literature search using the Embase, Scopus, Web of Science, CINHAL, Cochrane Library, and PubMed MEDLINE databases. We considered only studies focusing on adult patients and selected clinical studies investigating proximal fixation techniques.

resultsThere was mixed evidence of the efficacy of hooks and other instrumentation methods in preventing PJK, although most studies supported the use of hooks. Selection of lower thoracic vertebrae was associated with higher rates of PJK and PJF in several studies, although the relationship was inconsistent, and many studies reported no significant difference in rates of PJK or PJF between different upper instrumented vertebra (UIV) levels. Other techniques that are not related to specific instrumentation or vertebral selection, such as adjusting UIV screw trajectory, were also referenced. However, the evidence supporting these techniques was limited. DISCUSSION: Despite the presence of numerous studies in the literature discussing proximal fixation strategies to reduce the incidence of PJK/PJF, the lack of prospective studies and high variability in study methods make direct comparison challenging. We could not draw strong conclusions regarding the superiority of any one technique, despite promising clinical results with a strong biomechanical basis in several studies. CLINICAL RELEVANCE: This systematic literature review showed that a variety of proximal fixation techniques have been used to prevent PJK/PJF without clear evidence in favor of any particular technique.
