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

purposeTo evaluate hemodynamics in the sigmoid sinus of sigmoid sinus wall dehiscence (SSWD)-pulsatile tinnitus (PT) patients with idiopathic intracranial hypertension using four-dimensional (4D) flow MRI.

methodsThirty-five SSWD-PT patients with idiopathic intracranial hypertension were prospectively enrolled, together with 35 age-, sex-matched healthy controls and underwent MRI. Hemodynamics in the sigmoid sinus were evaluated by 4D flow MRI. Receiver operating characteristic curves and logistic regression analysis evaluated the ability of the hemodynamic indicators to differentiate SSWD-PT patients from healthy controls.

resultsPT patients presented significantly increased maximum velocity [86.77 ± 7.92 cm/s vs. 46.32 (38.89, 53.96) cm/s], maximum through-plane velocity (Vtp_max) (63.83 ± 16.89 cm/s vs. 45.65 ± 10.92 cm/s), backward flow volume [0.27 (0.06, 0.84) mL vs. 0.04 (0.01, 0.06) mL], regurgitant fraction [10.73 (2.11, 24.30) % vs. 0.47 (0.17, 1.31) %], and average wall shear stress (WSSavg) [0.27 (0.24, 0.33) N/m

conclusionSSWD-PT patients have hemodynamic changes in the sigmoid sinus. The combination of Vtp_max and WSSavg may serve as a valuable noninvasive indicator for differentiating SSWD-PT patients from healthy controls.
