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
Introduction: in Burkina Faso, blood transfusion is carried out with only ABO and RHD compatibility between the donor and the recipient. Such a practice carries risks of alloimmunisation, which can lead to clinical complications especially in polytransfused patients. The objective is to determine the prevalence and factors associated with alloimmunisation in polytransfused patients with non-phenotyped red blood cells at Souro Sanou University Hospital. Methods: we conducted a cross-sectional study in polytransfused patients in the clinical departments of the University Hospital Souro Sanou over a 3-month period (March to May 2019). In each of the 141 patients included, 5 ml of whole blood was collected in an ethylenediaminetetraacetic acid (EDTA) tube for testing for irregular antibodies. Irregular antibody testing was performed using the indirect Coombs gel filtration technical. Results: in total, the frequency of alloimmunisation obtained was 5.67%. The majority of the antibodies identified belonged to the Rhesus systems and Kell. We found no statistically significant relationship between age, sex, disease history, number of bags transfused and the positivity of the Irregular Antibody test (p = 0.37, p = 0, 75, p = 0.96). Conclusion: we found that the risk of alloimmunisation is major. Additional measures should be taken to strengthen the immunological safety of transfusions in Burkina Faso. We propose that in Burkina Faso, anti-globulin compatibility testing should be performed systematically in patients with a high risk of immunisation.
