Do Patients with Borderline Anemia Need Treatment before Total Hip Arthroplasty? A Propensity Score-Matched Cohort Study.
Article in Orthopaedic surgery, 2024. 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
objectivePreoperative anemia has been identified as a modifiable risk factor for multiple adverse outcomes. In real clinical practice, considering treatment of anemia would increase costs and delay surgery. Patients undergoing total hip arthroplasty (THA) with mild anemia are usually neglected and still underdiagnosed or inadequately treated. This study investigated the effects of preoperative borderline anemia and anemia intervention before THA on perioperative outcomes.
methodsWe screened 706 patients from those receiving THA at our hospital from January 2020 to January 2022, with 112 in the borderline anemia group and 594 in the non-anemia group. The cohort for this retrospective study was created by using propensity score matching (PSM) and subgroup analysis. The primary outcome was perioperative blood loss, while secondary outcomes were the rate of allogeneic blood transfusion and human serum albumin transfusion, perioperative laboratory indicators, postoperative length of stay, and complications. The independent sample t-test and the Mann-Whitney U-test were used to analyze continuous data, and the Pearson χ
resultsAfter PSM, there was no significant difference in perioperative blood loss between patients in the borderline anemia group and the non-anemia group. The primary outcomes of hidden (p = 0.004) and total (p = 0.005) blood loss were significantly lower in the intervention group than in the control group. No statistical differences were found in allogeneic blood transfusion, human serum albumin transfusion, postoperative length of stay, or complications (p > 0.05).
conclusionsAnemia treatments for patients with borderline anemia before THA significantly reduced hidden blood loss and total blood loss in the perioperative period and decreased the drop of hemoglobin and hematocrit without increasing postoperative complications.
