Investigating the association between blood transfusion and clinical outcomes in patients with acute coronary syndromes: a data linkage approach to Patient Blood Management.

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
backgroundThe appropriateness of the use of blood transfusion in patients with acute coronary syndromes (ACS) remains contested. In general, studies addressing this issue were based on data from clinical trials, registries, or electronic medical records, and were conducted across different settings. Our study aimed to use a linked patient blood management data system from existing hospital databases to examine the association between blood transfusion and in-hospital mortality, length of stay (LOS) and readmission rates among patients with ACS, and to investigate this relationship at different haemoglobin (Hb) concentrations. MATERIALS AND
methodsThis was a retrospective observational study of patients admitted to participating hospitals between 1
resultsOf the 9,952 admissions included, blood transfusions occurred in 705 (7.1%). In unadjusted analyses, transfusion was associated with an increased risk of in-hospital mortality (OR: 2.97; 95% CI: 2.14-4.13) and an average LOS 3.55 (95% CI: 3.38-3.72) times longer. After adjusting for demographic and clinical factors, transfusion was associated with an increased risk of in-hospital mortality when Hb >100 g/L. Transfusion was not associated with the risk of readmission. DISCUSSION: The effect of transfusion on in-hospital mortality was largely dependent on the pre-transfusion Hb concentration. When Hb was >100 g/L transfusion was associated with increased mortality, whereas when Hb ≤100 g/L no association was observed.
