Flow cytometry and thromboelastography to assess platelet counts and coagulation in patients with haematological malignancies.

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
backgroundAccurate platelet counts (PC) are necessary in order to follow recommendations for prophylactic platelet transfusion. We carried out a study comparing the standard way of counting platelets using a routine analyser and compared it with PC determined by flow cytometry (FC) and haemostatic data obtained with thromboelastography (TEG). MATERIALS AND
methodsThe study was carried out on 24 patients with haematological malignancies, all given one adult dose of platelets. The PC was determined before and after transfusion using an automated blood cell counter and FC. Citrated, "native" whole blood TEG was carried out before and after platelet transfusion to assess global haemostasis.
resultsNo bleeding was observed in any of the subjects. Thirty-one assessments were performed in the 24 patients. The mean pre-transfusion PC were 9.8 and 13×10(9)/L with the automated counter and FC, respectively with a difference of 3.7 (p=0.0011). Excellent correlation was observed between the two counts (r=0.89; p<0.0001). Mean post-transfusion increments were 23 and 29×10(9)/L for the routine counter and FC, respectively. Using the immunological PC, patients would not have qualified for transfusion in 18.2% of cases since their PC was >20×10(9)/L. TEG showed a shortened reaction time in 69.6% of cases and a normal mean K time of 6.7 min. Only 9% had a low α angle signifying hypocoagulability. The maximum amplitude was reduced in the majority of cases but normal in 25% despite PC<20×10(9)/L. Mean activated partial thromboplastin time, prothrombin time and fibrinogen were normal prior to transfusion. DISCUSSION: Although higher PC as assessed by FC could potentially have an impact on platelet transfusion practices, TEG was sensitive enough to detect PC<10×10(9)/L and some between 10-20×10(9)/L. Whether patients with the latter PC are more prone to bleeding remains to be verified in larger studies.
