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
purposeKyphosis is a potential complication after resection of cervical space-occupying lesions, and whether non-fusion surgery can maintain cervical stability remains controversial. We aimed to investigate long-term changes in neurological function and cervical curvature after non-fusion surgery in adults, and to further explore the prognostic factors.
methodsWe reviewed adult patients who underwent non-fusion surgery for resection of cervical space-occupying lesions at three neurosurgical centers. The neurological function grade defined by modified McCormick scale, the change of cervical Cobb lordotic angle (CLA), and the incidence of progressive kyphotic deformity and secondary fusion surgery were described. We also conducted regression analyses to explore the factors influencing CLA and neurological function.
resultsA total of 211 adults were enrolled in our study. The long-term follow-up showed that 84% patients achieved good neurological outcomes. The average change of CLA was 1.2 ± 7.2 degrees. There was no significant difference in CLA at follow-up compared with the preoperative value. Progressive kyphotic deformity was observed in 9(7%) patients and none of the patients underwent secondary spinal fixation surgery. Regression analysis identified LAMP surgery as a protective factor for CLA change (β = 5.519[1.994, 9.043]) while C-2 involvement as a risk factor (β=-3.433[-6.250, -0.616]).
conclusionsThe majority of patients undergoing non-fusion surgery for cervical space-occupying lesions achieve favorable neurological function and maintain ideal cervical curvature. Those patients whose C-2 were involved require more frequent follow-up.
