Transcranial Doppler ultrasonography in patients with hemoglobinopathy: An experience from a tertiary center.
Article in Northern clinics of Istanbul, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivePatients with hemoglobinopathy are prone to cerebrovascular event. Our aim was to screen the peak systolic flow velocity (PSV) using transcranial Doppler ultrasonography (TCD) in terms of cerebrovascular event risk in patients with beta thalassemia (β-thal) and sickle cell anemia (SCA).
methodsPSV and resistive index (RI) values were determined at internal carotid artery (ICA) and middle cerebral artery (MCA)-from both temporal regions using TCD.
resultsA total of 55 participants (40 patients and 15 healthy people) were included in the study. Thirty-three (60%) of the participants were female. Among 40 patients, 12 patients (30%) had NTDT, 14 patients (35%) had SCA, and 14 patients (35%) had TDT diagnosis. Bilateral ICA and MCA were open in all patients and had a normal flow pattern. PSV and RI were not significantly different between study and control groups in right and left MCA and ICA. Patients with high platelet level (>450.000/mm
conclusionPlatelet level and age of starting iron chelation might be an influencing factor for PSV. Regular follow-up of patients, appropriate therapy and lack of other factors causing cerebrovascular events might be possible reason for these acceptable results.
