A Nomogram to Predict Delirium after Hip Replacement in Elderly Patients with Femoral Neck Fractures.

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
objectivePostoperative delirium (POD) is a common complication, and clinical practitioners have taken measures to improve the quality of life after hip replacement surgery. We aim to establish a nomogram to predict POD in elderly patients with femoral neck fractures (FNFs) after hip replacement.
methodsA total of 384 elderly patients (267 females) with an average age of 75.8 years who underwent hip replacement from June 2010 to May 2020 were retrospectively reviewed. Patients were divided into delirium and non-delirium groups according to the confusion assessment method. The risk factors for POD were analyzed by multivariate logistic regression, and the nomogram was established based on the results.
resultsThe incidence of POD was 33.33% (128/384). Univariate analysis showed that advanced age, diabetes, lacunar cerebral infarction, surgery type, intraoperative blood loss, electrolyte imbalance, and anemia were risk factors for POD (p < 0.05). Multivariate logistic regression revealed that the independent risk factors for POD were age (OR = 1.332, 95% CI [1.224, 1.449], p < 0.01), surgery type (OR = 0.351, 95% CI [0.137, 0.900], p = 0.029), electrolyte imbalance (OR = 4.407, 95% CI [1.947, 9.977], p< 0.01), anemia (OR = 10.819, 95% CI [4.573, 25.598], p < 0.01). The prediction equation was established; logistic (p) = -25.469 + 0.277*X1(age[value = years of age]) + 1.293*X2(surgery[value = 0 for "total hip replacement" or value = 1 for "hemiarthroplasty"]) + 1.510*X3(electrolyte imbalance[value = 0 for "no" or value = 1 for "yes"]) + 2.157*X4(anemia[value = 1 for "hemoglobin with < 120g/L in male and < 110g/L in female patients" ]) or 2.975*X5(anemia[value = 1 for "hemoglobin with <90g/L"]). The area under the curve was 0.957 (95% CI [0.938, 0.976], p < 0.01).
conclusionThe incidence of POD in elderly patients with FNF after hip replacement is high. The nomogram incorporating age, surgery type, electrolyte imbalance, and anemia could provide an individualized prediction for POD among FNF patients after hip replacement, which may help the physician determine appropriate perioperative management.
