Practice patterns for neuroimaging and transfusion therapy for management of neurologic complications in sickle cell anemia: DISPLACE consortium.
Article in Pediatric blood & cancer, 2020. 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
backgroundChildren with sickle cell anemia (SCA) are at risk for neurologic complications (stroke and silent cerebral infarct). The 2014 National Heart, Lung, and Blood Institute (NHLBI) guidelines for sickle cell disease include recommendations for initiation and maintenance of chronic red cell transfusion (CRCT) therapy for children with SCA at risk for or with ischemic stroke. The guidelines do not include well-delineated recommendations for cerebral imaging for stroke screening. The purpose of this study was to evaluate current stroke risk screening, prevention, and intervention practices amongst the Dissemination and Implementation of Stroke Prevention Looking at the Care Environment (DISPLACE) study sites. PROCEDURE: A survey was administered to DISPLACE site principal investigators to identify current stroke prevention practices relative to the Stroke Prevention Trial in Sickle Cell Anemia (STOP) study protocols and the 2014 NHLBI guidelines. Data were analyzed using descriptive statistics and line-by-line analysis of comments.
resultsSites consistently applied NHLBI recommendations to initiate CRCT for ischemic stroke and abnormal transcranial Doppler ultrasound (TCD) results. Similarly, nearly all sites reported obtaining an magnetic resonance imaging (MRI)/magnetic resonance angiography (MRA) following an abnormal TCD result. There was wide variation for other indications for MRI/MRA, frequency of MRI/MRA, and other neurological indications for initiating CRCT.
conclusionsGuideline-based practices for preventing ischemic stroke through TCD and CRCT initiation were evident in nearly all sites. Wide variation in practices pertaining to MRI/MRA exists, potentially influenced by more recent stroke prevention trials. New guidelines from the American Society of Hematology were published in April 2020, which may reduce practice variation.
