Comparative Assessment of Echocardiographic Patterns Among Chronic Myeloid Leukemia Patients on Tyrosine Kinase Inhibitor and Healthy Controls.

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
purposeChronic myeloid leukemia (CML) is one of the common hematological malignancies in Nigeria. Cardiac abnormalities are associated with CML irrespective of treatment with tyrosine kinase inhibitors such as imatinib, which is available gratis in Nigeria.
objectiveTo assess the prevalence and patterns of cardiac dysfunction among patients with CML irrespective of treatment with imatinib using transthoracic echocardiography, and 12-lead surface electrocardiography. PATIENTS AND
methodsCML patients without Imatinib, CML patients with imatinib, and apparently healthy (age- and sex-matched) controls were 70 each in the study. Various echocardiographic parameters were measured and data obtained were analyzed, and the level of significance was taken as p < 0.05.
resultsOf 70 CML patients with imatinib, 54.3% were men and 45.7% were women, while the CML group without imatinib had 62.9% men and 37.1% women, non-CML control had 54.3% men and 45.7% women. The average hematocrit was significantly lower in the CML group without Imatinib compared with the other groups (p<0.001). And, 12.9% and 17.1% of CML groups with and without imatinib had LVH, respectively, and none of the non-CML controls had LVH (P<0.041). Impaired left ventricular relaxation in 25.71% and 28.57% of CML patients with and without imatinib respectively but only 8.57% of the non-CML control had impaired left ventricular relaxation (p=0.236). Mitral valve regurgitation was the most frequent valvular abnormality across the groups. Pulmonary hypertension in 17.4% and 20% of CML patients with and without imatinib, respectively, but none of the non-CML controls had pulmonary hypertension (p<0.001). Pericardial effusion in 32.86% and 45.71% of CML patients with and without imatinib, respectively, but none of the non-CML controls had pericardial effusion (p<0.001). There was no significant difference in the QTC interval across the three groups.
conclusionCardiac abnormalities are present in CML patients with or without Imatinib treatment, with significant prevalence than what is seen in the non-CML control group.
