Figure 1 Nomogram for assessing the risk of left atrial spontaneous echo contrast (LASEC) in patients with nonvalvular atrial fibrillation (NVAF). To use the nomogram, each variable was located on the corresponding variable axis, the number of points for each variable was determined by drawing a vertical line upward to the “Points” axis. Then, the total points were calculated by adding the number of points for all the variables. The sum numbers were located on the “Total Points” axis, and a vertical line was drawn down to the “Risk” axis to determine the risk of LASEC. AF – atrial fibrillation; TIA – transient ischemic attack. (R programming language, version 3.6.1, R Foundation) (Adobe Illustrator, version 2020, Adobe Inc.).
