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

purposeChiari malformation (CM) may occur in patients with craniosynostosis, and the presence of both in anatomically similar locations allows for simultaneous treatment. In this study, we analyze concurrent posterior vault distraction osteogenesis (PVDO) or posterior vault reconstruction (PVR) with extradural Chiari decompression for the management of suspected increased intracranial pressure (ICP) in patients with syndromic and atypical non-syndromic craniosynostosis.

methodsPatients who underwent concurrent PVDO/PVR and extradural Chiari decompression at a single institution from 2008 to 2024 were included. Of interest were patient/caregiver-reported symptomatology and radiographic findings related to CM reported by a board-certified neuroradiologist. Descriptive, Chi-square, and Fisher's exact tests were utilized for analysis.

resultsEight patients met the inclusion criteria. Fifty percent (n = 4) had syndromic craniosynostosis and 50% (n = 4) had non-syndromic craniosynostosis; half (n = 4) underwent PVDO, and half (n = 4) underwent PVR. One patient (12.5%) had a post-operative complication (distractor infection), with no long-term sequelae. One hundred percent (n = 8) had resolution of clinical symptoms at the first follow-up, and 85.7% (n = 6/7) at the last follow-up; 50.0% (n = 4) of patients had improvement, and 50.0% (n = 4) had a stable presentation of CM on post-operative imaging. While most patients with radiologic improvement in CM were in the PVDO group compared to PVR (75% (n = 3/4) vs. 25% (n = 1/4), p = 0.5), this study was underpowered to detect a significant difference between techniques.

conclusionsPosterior vault expansion with extradural Chiari decompression in patients with concomitant suspected increased ICP and craniosynostosis appears safe and relatively effective at extended follow-up. Additional study of its long-term effects, patient selection, and comparison of PVDO vs PVR is warranted.
