Single-level cervical disc arthroplasty is associated with higher early subsequent surgery rates and similar adjacent segment disease rates compared with anterior cervical discectomy and fusion.

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: Cervical disc arthroplasty (CDA) is a motion-preserving alternative to anterior cervical discectomy and fusion (ACDF), but its comparative long-term durability remains debated. This study aimed to compare short- and long-term postoperative outcomes following single-level CDA versus ACDF. Methods: A retrospective propensity-matched cohort study was performed using a large national administrative database. Adult patients undergoing single-level CDA or ACDF without prior spine surgery were identified and matched 1:1, yielding 3,138 patients per cohort. Outcomes were assessed at 1, 2, 5, and 10 years postoperatively. Results: At 1 year, CDA was associated with lower rates of pulmonary embolism/deep venous thrombosis (PE/DVT) [0.6% Conclusions: Single-level CDA was associated with higher early revision and subsequent surgery rates and similar ASD rates compared with ACDF. Although CDA showed lower rates of select complications, these differences may not outweigh the increased intermediate-term reoperation burden.
