Numerically, the relationship between PD and IQ did not reach statistical significance via the weighted median ( OR = 0.20, p = 0.21), simple mode ( OR = 0.87, p = 0.78), or weighted mode ( OR = 0.86, p = 0.69) ( Supplementary Table S2 ).

may not be significantno p-value reported

As seen in the forest plots, the results of individual SNPs may not be significant, and only when the results are combined can a reasonable result be obtained, which is the red line at the bottom, which reflects that high IQ increases the risk of PD under the IVW approach.
