1 · What the graph read from it

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.

2 · The registry

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

Introduction: Favorable clinical outcomes have been reported for cervical disc arthroplasty (CDA), particularly in preserving motion and reducing adjacent segment disease compared with anterior cervical discectomy and fusion. However, evidence on the uptake of CDA in clinical practice remains limited. This study aimed to analyze Australian population trends in CDA over the past 6 years. Methods: The 6-year incidence of CDA in adult patients from 2019 to 2024 was analyzed using the Medicare Benefits Schedule (MBS) database. Data were stratified by sex and year, with population adjustments to account for demographic changes over the study period. Results: A total of 4216 CDA procedures were performed in Australia under the MBS over the 6-year period. The annual mean case volume was 702.7 cases. Procedure volumes remained relatively stable from 2019 to 2021, with a reduction in case numbers thereafter. The highest concentration of procedures occurred in the 35-54 (62.28%) age group ( Conclusions: Although there is growing evidence supporting the safety and efficacy of CDA, its utilization in Australia has remained stable over the past 6 years, with the highest uptake among young to middle-aged patients. Further analysis of utilization trends may help identify factors influencing adoption and guide future surgical practice.
