A) Please help me in interpreting the below results based on the provided method and my hypothesis.
B) Please show me around 4 graphs/ figures to best represent the below results in relation to my hypothesised interest and the results.




Hypothesis Amplitude-amplitude coupling, specifically delta-beta and delta-alpha coupling, will be significantly higher in individuals with Major Depressive Disorder (MDD) compared to healthy controls. This coupling will be correlated with self-reported anxiety and depressive symptoms, suggesting that EEG cross-frequency correlations could be a potential biomarker of predisposition to affective disorders. Method This study involved 48 participants (24 MDD, 24 healthy controls) who met specific criteria. They completed psychological assessments and underwent a 3-minute EEG recording with eyes closed. The EEG data were processed to remove artefacts, and mean band power was computed for delta, alpha, and beta frequency bands at Fz. Mann-Whitney tests assessed between-group differences, while Spearman's rank correlation coefficients evaluated amplitude-amplitude coupling. An alpha level of .050 was used for statistical significance, with 1-tailed and 2-tailed significance reported accordingly.
