The relationship between preoperative predictive factors for clinical outcome in patients operated for lumbar spinal stenosis by decompressive laminectomy.

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
backgroundOur hypothesis was that by identifying certain preoperative predictive factors, we could favorably impact clinical outcomes in patients undergoing decompressive surgery for lumbar spinal stenosis (LSS).
methodsIn this retrospective study, there were 65 patients (2016-2018) with symptomatic LSS who underwent decompressive laminectomy without fusion. Their clinical outcomes were assessed utilizing the Oswestry Disability Index (ODI). Multiple preoperative variables were studied to determine which ones would help predict improved outcomes: gender, age, body mass index (BMI), general/neurological examination, smoking, and drug therapies (anxiolytics and/or antidepressants).
resultsAll patients demonstrated statistically significant improvement on the ODI. Multivariate analysis revealed that those with higher preoperative BMI had significantly lower ODI on 1-year follow-up examinations, reflecting poorer outcomes. Postoperatively, 44 patients (67%) exhibited lower utilization of anxiolytic medications, 52 patients (80%) showed reduced use of antidepressant drugs, and pain medications utilization was reduced in 33 patients (50%).
conclusionDecompressive laminectomy without fusion effectively managed LSS. It reduced patients' use of pain, anxiety, and antidepressant medications. In addition, we found that increased preoperative BMIs contributed to poorer postoperative outcomes (e.g., ODI values).
