Sex Differences in Opioid Prescriptions Following Anterior Cervical Spine Surgery.
Article in Spine open, 2026. 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
Study Design: Retrospective cohort study. Objective: Our objective was to compare postoperative opioid prescriptions between male and female patients following anterior cervical discectomy and fusion (ACDF) and cervical disc arthroplasty (CDA). Summary of Background Data: Sex differences in pain are well-established in basic science and clinical medicine; however, sex differences in postoperative pain management following spine surgery are less well-studied. Methods: The Marketscan Commercial Claims and Encounters database was queried for adults without a history of chronic opioid use who underwent ACDF or CDA from January 2017 through June 2021. Binary logistic regression analyses of filling an opioid prescription and generalized linear model analyses of total oral morphine milligram equivalents (MMEs) prescribed were performed. "Perioperative" prescription were defined as 30 days before to 14 days after surgery; "prolonged postoperative" was defined as 91 to 180 days after surgery. Results: For single-level ACDF (n=9844; 51.7% female), females were more likely to fill a prolonged postoperative prescription [aOR: 1.36; 95% CI: 1.18, 1.56; p<0.001] and filled lower perioperative MMEs than males [adjusted mean difference (AMD): -15.32; 95% CI: -28.52, -2.13; p=0.02].For multi-level ACDF (n=12,871; 52.5% female), females were more likely to fill a prolonged postoperative prescription [aOR: 1.16; 95% CI: 1.03, 1.30; p=0.02] and filled lower MMEs than males in the perioperative period [AMD: -27.47; 95% CI: -39.78, -15.17; p<0.001].Following CDA (n=3283, 48.8% female), females were more likely to fill a prolonged postoperative opioid prescription [aOR: 1.53; 95% CI: 1.17, 2.00; p=0.002], but there was no association between sex and perioperative or prolonged postoperative MME. Conclusions: These findings can guide the expectations on postoperative opioid prescribing after ACDF/CDA and warrant further studies to confirm the results and optimize postoperative pain management.
