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

purposeThere is no doubt that the best outcome achieved in Cauda equina syndrome (CES) involves surgical decompression. The controversy regarding outcome lies with timing of surgery. This study reports outcomes on a large population based series. Timing of surgery, Cauda Equina syndrome classification based on British Association of Spine Surgeons (BASS) guidelines and co-morbid illness will be assessed to evaluate influence on outcome. MATERIALS AND

methodsA retrospective review of all patients surgically decompressed for CES between 01/01/2008 to 01/08/2014 was conducted. Patients with ongoing symptoms were followed up for a minimum of 2 years. Cauda Equina Syndrome (CES) was classified according to the BASS criteria: CES suspicious (CESS), incomplete (CESI) and painless urinary retention (CESR). Time and symptom resolution were assessed.

resultsA total of 136 patients were treated for CES; 69 CESR, 22 CESI and 45 CESS. There was no statistical difference in age, sex, smoking status and alcohol status with regards to timing of surgery. No correlation between increasing co-morbidity score and poor outcome was demonstrated in any subgroupAll CESR/I patients demonstrated some improvement in bowel and bladder dysfunction post-operatively. No significant difference in improved autonomic dysfunction was demonstrated in relation to timing of surgery. CES subclassification may predict outcome of non-autonomic symptoms. Statistically better outcomes were found in CESS groups with regards to post-operative lower back pain (P 0.049) and saddle paraesthesia (P 0.02).

conclusionSurgical Decompression for CES is an effective treatment that significantly improves patient symptoms including bowel and bladder dysfunction Early surgical decompression <24 h from symptom onset does not appear to significantly improve resolution of bowel or bladder dysfunction.
