Volume and outcomes in posterior cervical fusion: Insights from a national inpatient analysis.
Article in Journal of craniovertebral junction & spine. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Context: Hospital procedural volume is often linked to outcomes and costs, but whether this relationship holds for posterior cervical fusion (PCF) remains unclear. Aims: The objective of this study was to evaluate whether hospital PCF volume is associated with complications, discharge disposition, and hospital costs. Settings and Design: Retrospective cross-sectional analysis of the National Inpatient Sample (NIS) from 2016 to 2022. Subjects and Methods: Elective PCF encounters were analyzed, with hospitals stratified by annual PCF volume (low, intermediate, high). Survey-weighted multivariable logistic regression estimated odds of cardiovascular complications, overall adverse events, and nonroutine discharge; linear regression assessed total costs and lengths of stay (LOS). Models adjusted for demographic, clinical, and hospital covariates. Statistical Analysis Used: Survey-weighted regression with odds ratios (ORs), coefficients, and 95% confidence intervals (CIs). Significance was set at Results: We included 163,230 weighted elective PCF cases. Baseline characteristics differed across volume groups ( Conclusions: Hospital PCF volume is tied to complications, nonroutine discharges, and higher costs, challenging the volume-outcome paradigm and underscoring adjustment for patient complexity and case mix in benchmarking and allocation.
