Mortality and clinical outcome of Italian patients undergoing orthopaedic surgery: effect of peri-operative blood transfusion.
Article in Blood transfusion = Trasfusione del sangue, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundBlood transfusion is a relevant issue for elderly and frail patients, as they are often anaemic and have chronic diseases. Transfusion of red blood cells (RBC) can potentially affect morbidity and mortality of elderly patients undergoing major orthopaedic surgery. MATERIALS AND
methodsWe carried out a retrospective analysis of 2,593 patients undergoing major orthopaedic surgery between 2013 and 2017 in a single research institution in the Region of Apulia. The aims of the study were: 1) to describe the characteristics of transfused patients according to a restrictive or liberal strategy of transfusion and haemoglobin (Hb) triggers and targets; 2) to investigate the effect of RBC transfusion on mortality and complications.
resultsOlder, women and patients with American Society of Anesthesiologists (ASA) score 3-4 were more often transfused. Those with lower admission Hb level had a higher risk of being transfused. Hb triggers were associated with the patients' age. A restrictive transfusion strategy was significantly more frequent in patients undergoing primary knee replacement and in those with higher estimated blood loss. We did not observe any significant difference of complications in patients transfused with a liberal vs restrictive strategy. Logistic regression correcting for potential confounders revealed that sex (males more than females), duration of stay in hospital, hip fracture and Charlson score >4 were good predictors of complications and/or mortality. Mortality was significantly higher in males and in older patients with ASA score 3-4. DISCUSSION: In this large cohort of Italian patients undergoing major orthopaedic surgery males were significantly more exposed than women to complications and in-hospital mortality. Furthermore, those undergoing urgent surgery because of hip fracture had a 3-fold higher chance of complications. Charlson score >4 and ASA 3-4 are good predictors of complications and mortality, respectively.
