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

backgroundCauda equina syndrome is a surgical emergency often caused by lumbar disc herniation. Spinal manipulative therapy is commonly used for lumbar spine disorders, but case reports have raised concerns it may precipitate cauda equina syndrome. One cohort study suggested no increased risk, although it did not focus on patients with lumbar spine disorders pertinent to cauda equina syndrome, such as disc herniation, stenosis, or radiculopathy/sciatica.

objectiveTo address this evidence gap, we tested the null hypothesis that there is no increased risk of cauda equina syndrome following spinal manipulative therapy among adults with these lumbar spine disorders compared to matched controls receiving physical therapist-led therapeutic exercise (PTE).

methodsUsing a retrospective cohort design, we queried a U.S. research network (TriNetX) including patients aged ≥18 years with a lumbar spine disorder and excluding those with preexisting cauda equina syndrome, incontinence, serious spinal pathology, and recent spine surgery/injection. Data spanned 2005-2025. Patients were divided into cohorts: (1) spinal manipulative therapy administered by a chiropractor or (2) PTE without spinal manipulative therapy. Propensity score matching controlled for confounding variables. Outcomes included the risk ratio of cauda equina syndrome (primary), and bladder catheterization and bowel incontinence as additional cauda equina syndrome markers (secondary).

resultsAfter matching, there were 34,376 patients in each cohort. Comparing the spinal manipulative therapy cohort to PTE cohort, the incidence and risk of cauda equina syndrome did not significantly differ (risk ratio=0.88 [95% CI, 0.43-1.79]; p = .715). The risk of bladder catheterization (risk ratio = 0.50 [95% CI, 0.39- 0.64]; p < .001) and fecal incontinence (risk ratio = 0.50 [0.37, 0.68]; p < .001) was significantly lower in the spinal manipulative therapy cohort.

conclusionAmong adults with lumbar disc herniation, stenosis, and/or radiculopathy, we did not identify an association between spinal manipulative therapy and an increased risk of cauda equina syndrome.
