Analysis of the Haematological Phenotype and Molecular Characteristics of Rare Abnormal Haemoglobin.
Article in Molecular genetics & genomic medicine, 2024. 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
backgroundHaemoglobinopathy refers to a group of common monogenic inherited conditions associated with variations in the haemoglobin molecule; however, there is relatively limited reporting on abnormal haemoglobinopathy in the Chinese population, especially rare abnormal haemoglobin (Hb). The aim of this study was to explore the clinical characteristics of haemoglobinopathy to supplement data for the epidemiological investigation of Hb variants in Guangdong province of China.
methodsPeripheral blood was collected from five patients (including a family) for Complete blood count, Hb electrophoresis, High-performance liquid chromatography analysis and degenerative globin body testing. Hb variants were further analysed by PCR and DNA sequencing.
resultsThe research subjects were diagnosed with different types of abnormal Hb. The blood routine of the Hb Fukuyama (HBB:c.232C>T) diagnosed individual showed microcytic hypochromic anaemia, with a lower Hb level (64 g/L), mean corpuscular volume (MCV) of 71.5 fL and mean corpuscular haemoglobin (MCH) of 21.5 pg. Individuals diagnosed with Hb Port Phillip (HBA2:c.275T>C) exhibit a MCH level that is slightly below average, at 26.4 pg. The Hb Saint Etienne (HBB:c.279C>G) diagnosed individual showed macrocytic hypochromic anaemia, and the proband had a low Hb level (116 g/L), MCV of 102.2 fL and MCH of 29.4 pg.
conclusionWe confirmed the presence of Hb Fukuyama (HBB:c.232C>T) in China for the first time. Three rare patients with the Hb Saint Etienne (HBB:c.279C>G) phenotype and one patient with Hb Port Phillip (HBA2:c.275T>C) phenotype were included. Our research enriches the gene mutation map of haemoglobinopathy in Guangdong province and improves the detection system of haemoglobinopathy for population prevention and eugenics.
