Patients With Hypoplastic Left Heart Syndrome Have a Shorter Superior Vena Cava.
Article in Annals of thoracic surgery short reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: The primary treatment for hypoplastic left heart syndrome (HLHS) is the Fontan pathway, which entails performing the Glenn procedure. We hypothesized that the superior vena cava in patients with HLHS was short. As the length of the superior vena cava influences the Glenn procedure, we compared its length between patients with HLHS and those with other congenital heart diseases. Methods: Patients with HLHS or its variant, patients with ventricular septal defects (VSD), and patients with pulmonary atresia with intact ventricular septum (PA/IVS)-including critical pulmonary stenosis-were enrolled in this study. The effective superior vena cava ratio (ESCVR), which is defined as the inferior border of the left brachiocephalic vein to the superior surface of the right pulmonary artery/height, was measured. Results: The median ESVCR of the HLHS, VSD, and PA/IVS patients was 12.54 mm/m, 17.96 mm/m, and 18.46 mm/m, respectively. ESVCR of the HLHS group was significantly smaller than that of the other groups ( Conclusions: Patients with HLHS have a relatively short superior vena cava, which may complicate the Glenn procedure.
