1 · What the graph read from it

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.

2 · The registry

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

introductionBased upon the Third National Health and Nutrition Examination Survey data, iron deficiency anemia is the cause of at least 20% of cases of anemia in adults over the age of 65. This is especially relevant in patients undergoing major orthopedic surgery as substantial perioperative blood loss is possible, leading to a high rate of allogeneic blood transfusion in total hip replacements, total knee replacements, and hip fracture repairs. SIGNIFICANCE: The results of this systematic review may be of interest to clinicians and hospital administrators evaluating the clinical efficacy and cost effectiveness of intravenous (IV) iron administration prior to major orthopedic surgery. MATERIALS AND

methodsThe original studies considered for this review included patients who were over 18 years of age, undergoing major orthopedic surgery, and who received an IV iron treatment in the preoperative setting. A total of 1083 articles were identified and reviewed. After removing duplicates, 1031 publications were screened, and 105 full-text studies were assessed for eligibility. A total of 98 were excluded and 7 articles remained which met the criteria for this review. The primary outcome examined in the included studies was the allogeneic blood transfusion rate. The secondary areas of interest were changes in serum hemoglobin, morbidity and mortality, length of stay, and cost effectiveness.

resultsThis systematic review found little evidence that IV iron therapy is effective at reducing transfusion in patients undergoing major orthopedic surgery.

conclusionsWe do not recommend preoperative IV iron therapy for all patients scheduled for major orthopedic surgery.
