Heart abnormality associates with a wide spectrum of psychiatric disorders: Evidence from Mendelian randomization analyses

Figure 1 A Mendelian randomization analysis of heart abnormality (exposure factor, longitudinal axis) to psychiatric disorders (outcome, horizontal axis). The odds ratio (OR) is represented by color code, with OR values greater than 1 shown in red, less than 1 shown in green, and close to 1 shown in blue. OR values become greater from the bottom to the top of the color bar. Statistical significance is indicated by the letter, while the absence of letters indicates no statistical significance. ^aP < 0.05. ^bP < 0.01. OR: Odds ratio.
