The characteristics of blood transfusion and analysis of preoperative factors associated with intraoperative blood transfusion in congenital heart surgery: a case-control study.
Article in Journal of cardiothoracic surgery, 2022. 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
purposeBlood transfusion is a common and life-saving procedure in congenital heart surgery (CHS), and it is critical for patients to identify risk factors prior to surgery. Our objective is to conduct an analysis of the preoperative factors that influence blood use during CHS and to offer guidance on preoperative blood preparation.
methodsA total of 1550 cases were retrospectively analyzed in our institution between May 2019 and June 2020. We determined whether to employ red blood cells (RBCs), platelets, and plasma as dependent variables; we treated the data from characteristics and laboratory tests as binary data, except for the Risk Adjustment for Congenital Heart Surgery (RACHS) methods as multinomial data, and finally taken into binary logistic regression analysis.
resultsThe total amounts of transfused RBCs, platelets, and plasma were 850.5 U (N = 713, 46%), 159 U (N = 21, 1.4%), and 1374.2 U (N = 953, 61.5%), respectively. Multivariate analysis found age (OR 0.142, 95% CI 0.099-0.203, P < 0.001), weight (0.170, 0.111-0.262, P < 0.001) RACHS method (RACHS2 vs. RACHS1, 3.444, 2.521-4.704, P < 0.001; RACHS3 vs. RACHS1, 9.333, 4.731-18.412, P < 0.001; RACHS4 vs. RACHS1, 31.327, 2.916-336.546, P = 0.004), and hemoglobin (0.524, 0.315-0.871, P = 0.013) to be independent risk predictors of RBC transfused volume; age (9.911, 1.008-97.417, P = 0.049), weight (0.029, 0.003-0.300, P = 0.029), RACHS method (RACHS3 vs. RACHS1, 13.001, 2.482-68.112, P = 0.002; RACHS4 vs. RACHS1, 59.748, 6.351-562.115, P < 0.001) to be platelets; and age (0.488, 0.352-0.676, P < 0.001), weight (0.252, 0.164-0.386, P < 0.001), RACHS method (RACHS2 vs. RACHS1, 2.931, 2.283-3.764, P < 0.001; RACHS3 vs. RACHS1, 10.754, 4.751-24.342, P < 0.001), APTT (1.628, 1.058-2.503, P = 0.027), and PT (2.174, 1.065-4.435, P = 0.033) to be plasma.
conclusionAlthough patients' age, weight, routine blood test, coagulation function, and protein levels should all be considered for preparing blood before CHS, the RACHS method is the most important factor influencing intraoperative blood transfused volume and should be considered first in clinical blood preparation.
