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

backgroundRepetitive transcranial magnetic stimulation (rTMS) has been reported to induce neurogenesis and angiogenesis. As increased neural activity can induce a hemodynamic response, we investigated the effect of rTMS on perfusion in patients with middle cerebral artery steno-occlusion.

methodsThis was a prospective, randomized, open-label, blinded end-point, pilot study. Patients were divided into two groups (rTMS intervention and non-intervention) which were both administered antiplatelet drugs to treat vascular steno-occlusion. In the intervention group, additional rTMS was performed on the area with stenosis and obstruction. Perfusion rates were compared using single-photon emission computed tomography / computed tomography (SPECT/CT).

resultsFrom June 2020 to May 2022, 16 patients were subjected to 1:1 randomization. Using the standardized uptake value ratio (SUVr) to quantify perfusion in the affected brain region, the corresponding SPECT/CT values before and after rTMS were obtained. Imaging analysis was compared between eight and seven patients in the rTMS and control groups, respectively. Based on the comparison between the target and ipsilateral cerebellum SUVmeans, four patients had a ≥ 20% increase in SUVr in the rTMS group and none in the control group. Changes in SUVr were significantly different between the initial and follow-up SPECT/CT in the rTMS group (p = 0.033); no significant difference was observed in the control group (p = 0.481).

conclusionWe observed a significant improvement in perfusion in the stimulation group in a perfusion test performed between 6 and 12 months after rTMS stimulation in stroke patients with steno-occlusion of the middle cerebral artery.
