Different scanning protocol to assess left atrial appendage thrombus in patients with atrial fibrillation by cardiovascular computed tomography.

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
To investigate whether we can rule out the left atrial appendage (LAA) thrombus in patients with atrial fibrillation (AF) using different scanning protocol by Cardiovascular Computed Tomography (CCT). We retrospectively reviewed the CCT images of 138 patients with AF to assess LAA thrombus. Patients with no thrombosis diagnosed by preoperative CCT should be confirmed using intraoperative findings as the reference standard. Patients diagnosed with thrombosis were then compared with TEE examination. Different CT scanning protocol were used to assess LAA thrombus according to individual differences. In 126 cases, there was no thrombus in the LAA evaluated by preoperative CCT, and it was confirmed in the subsequent radiofrequency operation. CCT has the accuracy of 100% in confirming the absence of thrombus in the LAA. Twelve thrombi were detected by CCT, eleven thrombi were detected by TEE. Only one patient had different results between CCT and TEE. We could use different CT scanning protocol to rule out LAA thrombus according to individual differences. In some special patients, LAA thrombus can be evaluated by CCT instead of TEE.
