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

backgroundPseudomeningocele, an extradural collection of cerebrospinal fluid (CSF), has only been rarely reported to occur spontaneously in conjunction with isthmic spondylolisthesis (with lysis) in the lumbar spine. CASE DESCRIPTION: A 68-year-old male presented with low back pain and neurogenic claudication of several years duration without any history of trauma, epidural spine injections, or spine surgery. Lumbosacral magnetic resonance imaging (MRI) revealed a grade-I L4-L5 isthmic spondylolisthesis with spinal canal narrowing and a posterior paravertebral collection consistent with CSF. The patient underwent a spinal decompression consisting of a complete L4 and partial L5 laminectomy, a bilateral L4-L5 instrumented fusion (due to the lysis defect), and closure of the CFS fistula. The histology analysis was compatible with a pseudomeningocele.

conclusionLumbar isthmic spondylolisthesis may lead to changes in the elastic properties of the underlying dura mater. Rarely, this may lead to meningeal tears and formation of a pseudomeningocele. Historically, one must always check for a prior epidural injection that could have resulted in this complication. Additionally, as most likely the case here, the lysis defect was responsible for the foraminal dural laceration resulting in the pseudomeningocele.
