Evaluation of Ventricular Dyssynchrony Measured by Tissue Doppler Indices in Fetuses of Diabetic Mothers: A Case-Control Study.

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
Background: This study aimed to evaluate the effects of overt maternal diabetes on fetal cardiac function. Methods: In this case-control study, 26 pregnant women with overt diabetes (the case group) and 26 women with uncomplicated pregnancies (the control group) were examined using tissue Doppler echocardiography. Cardiac function was assessed twice in the fetal period (18-22 weeks and 28 weeks of gestation) and once in the neonatal period (1 week postnatal). Fetal cardiac function was assessed using early-diastolic maximum velocity index (Em), end-diastolic maximum velocity index (Am), Em/Am, left ventricular myocardial function index (LVMPI), and interventricular mechanical delay index (IVMDI). Results: The case and control groups were not significantly different in maternal and gestational age in fetal Doppler evaluation. Em (P=0.007), Am (P<0.001), LVMPI (P=0.003), and IVMDI (P=0.026) were significantly higher in the case group than in the control group, while there was no significant difference in Em/Am (P=0.264). Eight fetuses (30.8%) of diabetic mothers had dyssynchrony, while no cases of dyssynchrony were seen in fetuses of non-diabetic mothers (P=0.004). Infants of diabetic mothers were 8.8 times more likely to develop adverse neonatal outcomes than infants of healthy mothers (RR: 8.8, 95% CI: 1.71 to 45.31, P=0.009). Conclusion: The findings of the current study revealed significant cardiac dysfunction and dyssynchrony in fetuses of diabetic pregnant women. Additionally, IVMDI and LVMPI can be used to predict adverse neonatal outcomes in pregnancies complicated with overt diabetes.
