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
Objective: To estimate the prevalence and evaluate the surgical outcomes of dorsolumbar junction spinal tumors at a tertiary care center in Pakistan. Methodology: This retrospective cohort study was conducted at Punjab Institute of Neurosciences, Lahore, including 35 patients operated for dorsolumbar junction (D11-L2) tumors between January 2021 and October 2024. Data extracted from records and PACS included demographics, presentation, imaging, operative details, histopathology, extent of resection, and outcomes. Tumors were classified by compartment and resection status, and primary outcomes were symptomatic improvement and complications. Data were analyzed descriptively using Microsoft Excel. Results: The cohort comprised patients with a mean age of 36.25 ± 16.7 years, with male predominance (54.3%, n=19). Intradural extramedullary tumors were most prevalent (80.0%, n=28), with neurofibromas being the most common histological type (51.4%, n=18). Predominant presenting symptoms included backache radiating to lower limbs (80.0%, n=28) and neurological deficits. A posterior surgical approach was used in all patients achieving gross total resection(GTR) and near total resection (NTR) in 85.7% of patients. Immediate symptom relief was reported in 57.1% (n=20) of patients, with a tumor recurrence rate of 8.6% (n=3). Complications included new neurological deficits (5.7%, n=2) and cerebrospinal fluid leakage (5.7%, n=2). Conclusion: This study highlights that dorsolumbar junction tumors in our Pakistani cohort were predominantly intradural-extramedullary, mainly neurofibromas and schwannomas, most often at D12-L1/L1-L2. Standard posterior approaches achieved effective resections with low complications and early symptomatic improvement. These findings demonstrate that with modern imaging and surgical expertise, centers in Pakistan can deliver care comparable to international standards, while larger multicenter studies are needed to validate and extend these results.
