Hidden blood loss and its risk factors after hip hemiarthroplasty for hip fracture in the elderly.
Article in Joint diseases and related surgery, 2026. 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
objectivesThis study aims to evaluate hidden blood loss (HBL) and its determinants in elderly hip fracture patients undergoing this procedure via a posterolateral approach. PATIENTS AND
methodsBetween January 2016 and June 2024, a total of 105 patients (52 males, 53 females; mean age: 78.5±5.6 years; range, 60 to 93 years) who underwent hip hemiarthroplasty through a posterolateral approach were retrospectively analyzed. Patient demographics and clinical data were obtained. Pre- and postoperative hematocrit (Hct), height, and weight were documented. Perioperative total blood loss (TBL) and HBL were quantified using the Gross and Sehat formulas, respectively. Risk factors linked to HBL were determined.
resultsThe mean operative duration was 80.3±9.9 min. The mean HBL was 465.9±58.3 mL, accounting for 81.4% of TBL (571.1±149.6 mL). Multivariate linear regression revealed significant associations between increased HBL and lower preoperative albumin (β=-0.188, p=0.011), higher American Society of Anesthesiologists (ASA) classification (β=0.162, p=0.029), and perioperative blood transfusion (β=0.221, p=0.002).
conclusionHidden blood loss constitutes a clinically significant consideration during hip hemiarthroplasty for geriatric hip fractures. Significantly greater HBL occurs in patients with preoperative hypoalbuminemia, elevated ASA classification, or perioperative transfusion. Recognizing and quantifying HBL enhances perioperative assessment precision and contributes to improved patient safety.
