Fig. 2

A volcano plot for visualizing statistical significance (p-values) and the magnitude of alarm signals (reporting odds ratios; RORs) for 18 PTs. RORs were calculated using the reported data to which reporters had higher certainly about causality (primary and secondary suspected) for prednisolone, methylprednisolone and dexamethasone

Negative common logarithm (to the base 10) of p-values (−log10 P) are plotted on the y-axis and natural logarithm (to the base e) of RORs (ln ROR) are plotted on x-axis. The horizontal line represents the threshold of significance (p = 0.05) corrected for multiple comparisons by Bonferroni’s method (p = 0.00093)
