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

backgroundThe majority of patients presenting with suspected clinical cauda equina syndrome (CES) have no identifiable structural cause for their symptoms ('scan-negative' CES). Understanding these patients aids clinical differentiation and management in CES.

methodsA retrospective electronic note review was undertaken of patients presenting with suspected CES, defined as ≥ 1 of acute bladder, bowel, sexual dysfunction or saddle numbness, to a regional neurosciences centre. We investigated radiology, clinical features, psychiatric and functional disorder comorbidities and outcome of patients with 'scan-negative' CES and patients with MRI confirmed compression of the cauda equina ('scan-positive' CES).

results276 patients were seen over 16 months. There were three main radiologically defined patient groups: (1) 'scan-positive' CES (n = 78, mean age 48 years, 56% female), (2) 'scan-negative' CES without central canal stenosis but with lumbosacral nerve root compression not explaining the clinical presentation (n = 87, mean age 43 years, 68% female) and (3) 'scan-negative' CES without neural compromise (n = 104, mean age 42 years, 70% female). In the two 'scan-negative' groups (no neural compromise and nerve root compression), there were higher rates of functional disorders (37% and 29% vs. 9%), functional neurological disorders (12% and 11% vs 0%) and psychiatric comorbidity (53% and 40% vs 20%). On follow-up (mean 13-16 months), only 1 of the 191 patients with 'scan-negative' CES was diagnosed with an explanatory neurological disorder (transverse myelitis).

conclusionsThe data support a model in which scan-negative cauda equina syndrome arises as an end pathway of acute pain, sometimes with partly structural findings and vulnerability to functional disorders.
