Symptomatic Lumbar Discal Cyst: A Rare Entity that Can Mimic Other Lumbar Cystic Lesions.
Article in Cureus, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
Lumbar discal cyst (LDC) is a rare clinical entity with unclear etiology. Three theories have been proposed to describe the pathogenesis of this condition: (i) a reaction to spinal epidural hematoma; (ii) a pseudomembrane formation that follows the focal annular tear and disc degeneration; and (iii) an inflammatory reaction to the herniated disc fragment. It usually presents with radicular symptoms. Radiographically, LDC can mimic other cystic lesions of the lumbar spine. Imaging nuances such as scalloping of the vertebral body, contrast filling with discography, and MRI signal intensity on different sequences can help to establish a diagnosis of LDC. However, there are no clear guidelines on the best treatment approach. Several treatment options have been prescribed to treat LDC with good outcomes. Here we describe a case of LDC that presented with left-sided radicular symptoms for several months and had not undergone any initial conservative management. The patient was treated successfully with microscopic resection of the cyst with complete resolution of the symptoms.
