Perioperative Factors Associated With Allogeneic Blood Transfusion in Elective THA.
Article in Orthopaedic surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundIdentifying predictors of perioperative blood transfusion is essential for optimizing patient safety and perioperative blood management in total hip arthroplasty (THA). This Study aimed to identify perioperative factors independently associated with transfusion.
methodsThis retrospective study included all elective primary THA procedures performed between 2016 and 2023 at a certified Endoprosthetic Center. Demographic, clinical, laboratory, and operative variables were extracted. Total and hidden blood loss were calculated using the Nadler and Gross/Sehat formulas. A multivariable logistic regression model was fitted to identify independent factors associated with transfusion. Receiver operating characteristic (ROC) analyzes were performed for cup inclination and the 48-h hematocrit. Cutoff thresholds were derived using Youden's index, and combined decision rules (AND/OR) were evaluated.
resultsAmong 39 predictors, three variables were independently associated with transfusion: cup inclination (OR = 0.89; p = 0.0003), 48-h hematocrit (OR ≈5.17 × 10
conclusionEarly postoperative hematocrit is a robust and clinically actionable marker associated with transfusion risk in primary THA. Cup inclination reflects the surgical technique rather than direct transfusion risk, and reoperation likely indicates underlying perioperative complexity. Transfusion strategies should prioritize hematocrit-based evaluation rather than inclination-based thresholds. LEVEL OF EVIDENCE: III-retrospective single-center observational cohort study.
