Predictive value of perioperative D-dimer to albumin ratio for postoperative serious medical complications and one-year mortality in elderly patients with hip fracture: a retrospective study.
Article in BMC geriatrics, 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
backgroundElderly patients carry high risks of postoperative serious medical complications (PSMC) and mortality, but reliable perioperative predictive indicators remain limited.
objectiveTo evaluate the predictive value of perioperative hematological markers for PSMC and 1-year mortality in elderly surgical patients.
methodsA total of 590 patients aged 65-85 years were enrolled. Perioperative blood parameters were measured preoperatively and on postoperative days 1, 3, 5, 7. Patients were grouped by PSMC occurrence and 1-year survival status. ROC analysis was used to assess diagnostic performance.
resultsPSMC occurred in 58 patients (9.8%), and 89 patients (15.08%) died within 1 year. Perioperative red blood cells, hemoglobin, albumin, creatinine, procalcitonin, troponin, D-dimer, and D-dimer to albumin ratio (DAR) showed significant dynamic changes (all p < 0.01). The PSMC group had lower albumin and higher D-dimer and DAR than the non-PSMC group (all p < 0.01), with markedly higher 1-year mortality (86.21% vs. 7.33%, p < 0.001). Preoperative DAR showed the comparable predictive power for PSMC (AUC = 0.82), followed by D-dimer (AUC = 0.80) and albumin (AUC = 0.69). For 1-year mortality, D-dimer and DAR both had an AUC of 0.74, with DAR exhibiting higher sensitivity (85.39%). Elevated DAR was significantly associated with increased PSMC and mortality risks (both p < 0.001). Multivariate logistic regression showed high DAR was an independent risk factor for PSMC (OR = 26.82, p < 0.001) and 1-year mortality (OR = 21.75, p < 0.001).
conclusionPerioperative DAR is a promising prognostic biomarker for PSMC and 1-year mortality in elderly surgical patients. High DAR indicates poor prognosis and may help identify high-risk individuals for targeted intervention.
