Prevalence and factors associated with preoperative anemia among adult patients scheduled for major elective surgery at University hospital in Northwest Ethiopia; a cross-sectional study.
Article in Heliyon, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundAnemia is the most common hematological finding in surgical patients. One-third of surgical patients were anemic during preoperative assessment. The presence of preoperative anemia was found to be related with increased morbidity, mortality, length of hospital stay, intensive care unit admissions and postoperative infections.
objectiveTo determine the prevalence and factors associated with preoperative anemia among adult patients scheduled for major elective surgery at University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia, 2020.
methodsAfter obtaining an ethical approval, hospital-based cross-sectional quantitative study was conducted from June to August 2020 in University of Gondar Hospital. Full blood count within two weeks of preoperative period was considered valid if there were no any factors that affect the hematologic system Descriptive statistics, cross-tabulations and binary logistic regression analysis were performed to identify factors associated withpreoperative anemia. The strength of the association was presented using AOR with 95% confidence interval and p-value < 0.05 was considered as statistically significant.
resultA total of 185 patients enrolled with 100% response rate. We observed preoperative anemia in 36.8% patients. The multi-variable binary logistic analysis showed that ASA II and III [AOR: 3.8, CI: 1.6-9.2], recent prior surgery [AOR: 3.3, CI: 1.3-8.5], history of malignancy [AOR: 9.4, CI: 2.0-43.4], orthopedic procedure [AOR: 11.2, CI: 4.0-31.6] and gynecologic procedure [AOR: 5.2, CI: 1.7-14.5] were significantly associated with preoperative anemia.
conclusionThe prevalence of preoperative anemia was high and ASA ≥2, recent prior surgery, history of malignancy, orthopedic surgery and gynecologic procedure were significantly associated with preoperative anemia. We recommend to clinicians to aim prevention, early detection and treatment of preoperative anemia among adult patients scheduled for major elective surgery to reduce risk of anemia and related adverse outcomes.
