Synthesis in Neurosurgical review, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05636917 (Study of the Diagnostic Accuracy of the Slump and Straight Leg Raise Neurodynamic Tests in Patients With Clinical Suspicion of Lumbar Radiculopathy), which is not on this map. Cited by 20 papers, 1 of them a synthesis that pooled it.

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.

Abstract

Lumbar disc herniation (LDH) is a relatively common pathology usually presenting with unilateral radiculopathy ipsilateral to the disc herniation. Some patients can present with contralateral radicular symptoms. The objective of this article is to review the current literature on lumbar disc herniations with contralateral radiculopathy regarding its pathophysiology and surgical strategies. A systematic review of the literature on LDH with contralateral radiculopathy was performed using MEDLINE (via PubMed) using MeSH terms. This review was done following recommendations of PRISMA statement and PICOT strategy of search. Initial electronic search identified 126 papers. Finally, 18 articles were reviewed. None of the included papers was described as comparative. Pathophysiological processes underlying contralateral pain may include prominent spondylotic changes and the accompanying stenosis; hypertrophic yellow ligament; dural attachments along the posterior longitudinal ligament; nerve root traction forces; and friction radiculitis, migrated epidural fat, nerve root anomaly, and venous congestion inside the vertebral canal. In our pooled analysis, 11 patients reported were treated by bilateral approach with 100% of clinical success and no complications. Eight patients were treated by unilateral approach ipsilateral to pain with 100% of clinical success and no complications. Forty-eight patients were treated by unilateral approach ipsilateral to herniation with 100% of clinical success and no complications. Pathophysiology underlying contralateral pain in LDH is probably multifactorial. There is not enough scientific evidence to define the best surgical approach for patients with LDH and contralateral pain.
