Assessment of Clinical and Radiologic Outcomes of Biportal Endoscopic Posterior Cervical Inclinatory Foraminotomy : A Retrospective Cohort Study.
Article in Journal of Korean Neurosurgical Society, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveTo evaluate clinical and radiological outcomes of biportal endoscopic posterior cervical inclinatory foraminotomy (BE-PCIF) to treat cervical spondylotic radiculopathy (CSR).
methodsThis retrospective study included patients with CSR who underwent BE-PCIF between April 2020 and April 2023. Patient demographic data were collected and clinical outcomes were assessed using the Visual analog scale (VAS) and MacNab criteria. Various radiological parameters, including inclinatory angles, were collected and correlations with demographic or radiological factors were evaluated.
resultsWe included 101 patients (46 men and 55 women) with a mean age of 56.99 years, encompassing 162 surgical levels primarily affecting the C5-6 and C6-7 vertebrae. The postoperative VAS scores decreased to less than 1, with 90.1% of patients reporting excellence according to the MacNab criteria. None of the patients experienced any major postoperative complications, including instability. The isthmic distance (ID) expansion ratio, representing the degree of distal decompression, was 2.4, with a minor facet resection rate of 0.4. Right-sided surgeries or surgeries at lower cervical levels correlated with higher inclinatory angles, with a p-value of 0.003 each. Significant correlations were noted between the inclinatory angle and both the facet resection rate and ID expansion ratio, with coefficients of 0.45 and 0.3, respectively, both having a p-value of <0.001, indicating strong statistical significance.
conclusionBE-PCIF effectively relieves pain and enhances clinical outcomes in CSR patients. The use of the inclinatory angle approach facilitates cervical foraminal expansion and sufficient neural decompression, with higher angles required for adequate decompression at lower cervical levels.
