Prevalence of Chromosome 7 Abnormalities in Myelodysplastic Syndrome and Acute Myeloid Leukemia: A Single Center Study and Brief Literature Review.

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
Chromosome 7 abnormalities in patients with myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) heralds a poor prognosis. However its prevalence, morphological characteristics and clinical impact in MDS and AML in Indian subcontinent is sparsely reported. This was an observational cross-sectional study performed to evaluate the clinico-pathological profiles of MDS/AML patients with chromosome 7 abnormalities over a period of 4 years. 724 cases of MDS (n = 150) and AML (n = 574) were evaluated. Abnormal karyotype was detected in 49% (43/88) patients of MDS and 44% (127/289) cases of AML. Chromosome 7 abnormalities were detected in 18% cases of MDS (16/88) and 6.5% (19/289) cases of AML. Sole chromosome 7 abnormalities were detected in 5.7% (5/88) and 2.7% (8/289) and in adjunct to complex abnormalities in 7.9 and 3.1% cases of MDS and AML respectively. Morphologically, dyserythropoiesis, dysmyelopoiesis and eosinophilia were seen in 100, 66 and 56% cases of MDS and 38, 40 and 21% cases of AML. Majority of the patients had an aggressive natural course and outcome was dismal. Chromosome 7 abnormalities are strongly associated with the presence of morphological dysplasia and eosinophilia, irrespective of the type of aberration. It is invariably associated with very poor outcome.
