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

This letter to the editor comments on a recent computational fluid dynamics study by You et al. on hemodynamic features of offending arteries in hemifacial spasm (HFS). While the original study provides valuable insights into arterial compression, it omits venous offenders and multi-vessel compression scenarios. Drawing on clinical cases and surgical evidence, this letter highlights the independent role of veins (e.g., the vein of the middle cerebellar peduncle) and the complexity of vertebral artery involvement. It argues that future CFD studies should include venous etiologies and multi-vessel configurations to improve diagnostic accuracy and surgical planning. The hemodynamic differences between arterial and venous compression are discussed, and the potential utility of parameters such as TAWSSR for venous offenders is proposed.
