Healthcare Resource Utilization and Cost Comparison Between Palbociclib, Abemaciclib, and Ribociclib Among Patients with HR+/HER2- Metastatic Breast Cancer.
Article in ClinicoEconomics and outcomes research : CEOR, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Purpose: To evaluate economic outcomes in patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2-) metastatic breast cancer (mBC) treated with a first- or second-line cyclin-dependent kinase 4/6 inhibitor (CDK4/6i). Methods: This retrospective analysis utilized Optum's Clinformatics DataMart (January 1, 2014-September 30, 2021). Included patients had ≥1 pharmacy claim for palbociclib, abemaciclib, or ribociclib in first or second-line and ≥6 months of continuous health plan enrollment in preindex (index: date of first CDK4/6i claim) and follow-up periods. Mean all-cause per patient per month (PPPM) medical, healthcare resource utilization (HCRU) and costs, and outpatient pharmacy prescriptions costs were compared among CDK4/6is using stabilized inverse probability of treatment weighting (sIPTW). Results: We identified 3,182 patients taking palbociclib, 286 taking abemaciclib, and 149 taking ribociclib, with median follow-ups of 20.8, 16.6, and 19.9 months, respectively. After sIPTW, palbociclib was associated with a lower risk of inpatient (IP) admissions versus abemaciclib (35.8% vs 41.6%; odds ratio: 1.31; Conclusion: All-cause HCRU and costs were generally not different between the CDK4/6is but favored palbociclib for medical (including IP) costs versus abemaciclib. Due to limited patient numbers, uncertainty exists about abemaciclib and ribociclib cost estimations. Further studies of HCRU and costs are needed to support a cost-minimizing strategy for mBC.
