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
purposeTo assess and compare the preoperative healthcare costs associated with single-level cervical disc arthroplasty (CDA) and anterior cervical discectomy and fusion (ACDF), with additional evaluation across cost categories and insurance types.
methodsPatients who underwent CDA or ACDF between 2010 and 2022 were queried from the PearlDiver Mariner database. Preoperative expenditures - including office visits, imaging (X-ray, MRI, CT), opioid prescriptions, steroid injections, and physical therapy - were quantified. Patients were stratified by insurance type, and statistical comparisons were performed using t-tests with significance set at P < 0.05.
resultsCDA was associated with significantly higher preoperative costs compared to ACDF. The mean total preoperative cost for CDA was $10,967.98 versus $9,463.64 for ACDF (P < 0.001), driven by greater expenditures on physical therapy, imaging, and office visits. Among Medicare beneficiaries, CDA patients had preoperative costs of $9,517.83 versus $9,178.40 for ACDF (P < 0.001), with significant differences in imaging. In the commercial insurance cohort, CDA patients incurred $11,062.86 compared to $9,226.20 for ACDF (P < 0.001), with larger differences in physical therapy, imaging, and office visits.
conclusionCDA incurs higher preoperative costs than ACDF across both Medicare and commercial insurance groups, with notable differences in physical therapy and imaging expenditures. These findings underscore the importance of evaluating cost drivers in the preoperative setting and highlight the potential for cost-optimization strategies, particularly in patients undergoing CDA.
