Dear Lydia,

Thank you for your prompt response! I sincerely regret the null results produced by my data, prompting me to explore alternative avenues. I am seeking guidance on the feasibility of amalgamating rs-fMRI and task-fMRI studies for a meta-analysis. If this isn't advisable, I would appreciate any suggestions on how to proceed with my null results.

I'm also interested in understanding the impact of t-values from each study included in the meta-analysis. Typically, these values are either reported directly or derived from p-values or z-values. The common parameters include an uncorrected p-value of 0.005 or a corrected p-value of 0.05 (or 0.01). By considering various sample sizes, we can obtain the respective t-values for each study. My current understanding is limited to these aspects, and I am uncertain whether the null results stem from a small sample size or incorrect t-values resulting from a misunderstanding on my part.

In conclusion, I greatly appreciate your insights, and I eagerly await your response. I am determined not to give up and am committed to exploring potential solutions.

Best regards, 

Shiyi
