Comparative predictive performance of HALP score and prognostic nutritional index for mortality in ICU patients after hip fracture surgery.
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
backgroundHip fractures in elderly patients are associated with high morbidity and mortality. Simple and reliable prognostic biomarkers are needed to complement clinical risk assessment Hemoglobin-Albumin-Lymphocyte-Platelet (HALP) score and Prognostic Nutritional Index (PNI) reflect nutritional and immunological status and may predict postoperative outcomes. We aimed to investigate the association of preoperative HALP score and PNI with 1-year all-cause mortality in elderly patients admitted to the intensive care unit (ICU) after surgical treatment for hip fractures.
methodsA retrospective study was performed on 257 patients aged 65 years and older who were admitted to the ICU following surgical intervention for hip fractures. Demographic information, comorbidities, and laboratory results were all gathered. The patients were categorized into two groups: non-survivors (n = 40) and survivors (n = 217). Univariable and multivariable Cox regression analyses were performed to identify independent predictors of 1-year all-cause mortality.
resultsNon-survivors had significantly lower PNI (34.1 ± 7.7 vs. 37.9 ± 6.6; p = 0.004) and HALP scores (median 11.3 vs. 17.3; p = 0.003). Two separate multivariable Cox regression analysis models were performed for PNI and HALP. In both models, male gender, malignancy, and a high Charlson Comorbidity Index were identified as independent predictors of mortality. While HALP was not an independent predictor of mortality in the multivariable analysis, low PNI (HR 0.928; 95% CI 0.874-0.987; p = 0.017) was found to be an independent predictor of all-cause mortality at 1 year. ROC analysis demonstrated limited discriminative power for PNI (AUC 0.642) and HALP (AUC 0.648).
conclusionsPreoperative PNI was an independent predictor of mortality in elderly hip fracture patients, whereas HALP showed limited prognostic value. These simple nutritional indices may aid early risk stratification and guide perioperative care.
