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: Spontaneous coronary artery dissection (SCAD) is increasingly diagnosed as one of the infrequent causes of acute coronary syndrome. Almost no cause was identified in half of the cases. Here, we report a rare case of spontaneous coronary artery dissection with leucoencephalopathy (SCADLE) associated with a mutation of the thrombospondin Type 1 domain containing 1 (THSD1) gene. Case summary: A 36-year-old lady who presented with ischaemic type chest pain for 4 h duration and found to have anterior ST elevation myocardial infarction. She was thrombolysed with tenecteplase and had good resolution. Her coronary angiogram revealed a spontaneous dissection in the left anterior descending artery (LAD) with TIMI 3 flow. Intra-vascular ultrasound study confirmed the LAD spiral dissection and intramural haematoma. She has had recurrent transient ischaemic attacks 5 years and 7 years ago, and there was a significant family history of young stroke. Her magnetic resonance imaging (MRI) brain showed peri-ventricular white matter hyper-intensities and lacunar infarcts suggestive of leucoencephalopathy. An association with cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) and SCAD was suspected, and exome gene sequencing followed by genetic analysis was performed. It identified a variant c.67°C > G (p. Arg224Gly) in the THSD1 gene with normal NOTCH gene. Discussion: Thrombospondin Type 1 domain containing 1 gene encodes proteins involving in the extra-cellular matrix (ECM). This THSD1 mutation is inherited as an autosomal dominant fashion and associated with arterial dissections (rare), fibromuscular dysplasia, intra-cranial aneurysm, and subarachnoid haemorrhages. Therefore, SCADLE could be a result of arteriopathy secondary to dysfunction of ECM proteins in cerebral and coronary vasculature resulting in neurological manifestations and MRI features like in CADASIL and SCAD.
