Perioperative antithrombotic management in degenerative spine surgery: a multicenter cohort of 767 consecutive patients.

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
Background: Perioperative management of antithrombotic therapy in degenerative spine surgery remains a challenging clinical issue, particularly in elderly patients with cardiovascular comorbidities requiring chronic anticoagulant or antiplatelet treatment. Although several guidelines address perioperative anticoagulation in high-bleeding-risk procedures, procedure-specific evidence in elective spinal surgery remains limited, and clinical practice is still heterogeneous. Methods: A multicenter retrospective cohort study was conducted including 767 consecutive patients aged 60 years or older who underwent elective surgery for degenerative spine disease. Surgical procedures included anterior cervical discectomy and fusion, lumbar microdiscectomy for disc herniation, decompression for lumbar spinal stenosis, and monosegmental posterior lumbar interbody fusion. Patients were stratified according to perioperative antithrombotic management into three groups: no chronic antithrombotic therapy, perioperative low-molecular-weight heparin substitution, and temporary perioperative substitution with low-dose aspirin. Intraoperative hemoglobin loss, operative time, postoperative length of stay, and perioperative complications were compared across groups. Results: Perioperative outcomes were similar among the three antithrombotic management groups across all procedures. Intraoperative hemoglobin loss, operative duration, and postoperative hospitalization showed no significant differences between patients undergoing low-molecular-weight heparin substitution or aspirin continuation and those without chronic antithrombotic therapy. No cases of postoperative spinal epidural hematoma requiring evacuation, myocardial infarction, stroke, deep venous thrombosis, or pulmonary embolism were observed. The observed between-group differences in hemoglobin loss, operative time, and postoperative hospitalization remained within the predefined clinically meaningful margins. Conclusion: In this multicenter cohort of 767 consecutive patients undergoing common degenerative spine procedures, perioperative antithrombotic management based on low-molecular-weight heparin substitution or low-dose aspirin substitution was not associated with clinically relevant worsening of perioperative outcomes when compared with patients not receiving chronic antithrombotic therapy. These findings suggest that structured perioperative antithrombotic protocols may represent a reasonable strategy in elective degenerative spine surgery.
