Comparing Hospital-Free Days by Frailty Status for Patients Undergoing Surgical Intervention for Cardiovascular Disease.
Article in Journal of the American College of Surgeons, 2025. 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
backgroundAging patients face increasing comorbid conditions, most commonly atherosclerotic cardiovascular diseases, which are often treated surgically; however, aging is also associated with frailty, which portends adverse postoperative outcomes. Assessing outcomes in a frail surgical cohort necessitates the use of valid patient-centered metrics such as hospital-free days (HFDs) quantifying patient time at home and out of the hospital. STUDY
designWe included patients from the Florida State Inpatient Database undergoing coronary artery bypass grafting, carotid endarterectomy, or abdominal aortic aneurysm repair (2015 to 2018). The association between frailty (Risk Analysis Index) and 90-day HFD (HFD-90) was assessed using multivariable zero-inflated negative binomial and ordinal logistic regression models. Logistic regression evaluated the association between frailty and in-hospital mortality.
resultsOverall, 67,861 patients (age 69.3 ± 9.9 years; 28.3% women; 46.4% robust, 46.6% normal, and 7.0% frail) were included from 148 Florida hospitals. Median HFD-90 was 83 (interquartile range 79 to 86) days, and 2.6% of patients experienced in-hospital mortality. Compared with normal status, robust status was associated with higher HFD-90 (adjusted rate ratio 1.03, 95% CI 1.02 to 1.04), whereas frailty was associated with lower HFD-90 (adjusted rate ratio 0.95, 95% CI 0.94 to 0.96) risk. Similarly, robust patients had lower adjusted odds of in-hospital mortality (adjusted odds ratio 0.40, 95% CI 0.34 to 0.48), whereas frail patients had higher odds (adjusted odds ratio 6.20, 95% CI 4.90 to 7.77) as compared with normal.
conclusionsHFD-90 is a feasible, comprehensive, patient-centered metric to assess outcomes in frail patients which encompasses the most used postoperative outcomes assessment tools (mortality, length of stay, and readmission) into 1 inclusive measure.
