1 · What the graph read from it

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.

2 · The registry

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

Objective: This study aimed to evaluate the hemodynamic characteristics of fetuses with isolated Aberran Right Subclavian Artery (ARSA) and compare them with a control group of normal fetuses using Doppler ultrasonography. Methods: A total of 93 fetuses were included in this prospective case-control study. Forty fetuses with isolated ARSA and 53 control fetuses with normal right subclavian arteries were analyzed. Doppler ultrasonographic parameters (Peak Systolic Velocity (PS), Pulsatility Index (PI), Resistive Index (RI), Time-Averaged Maximum Velocity (TAMAX), Heart Rate (HR)) were assessed and compared between the two groups. Results: No significant differences were found in the Doppler parameters (PS, PI, RI, TAMAX, HR) between the ARSA and control groups. Furthermore, there was no correlation between gestational age, fetal weight, and Doppler parameters in either group. Conclusion: The study supports the hypothesis that isolated ARSA is a benign anatomical variant without significant hemodynamic impact on fetal development. ARSA cases without associated cardiac or chromosomal anomalies do not appear to affect fetal growth.
