It is possible to retrieve correlations from raw means, sd, and t-values (by solving the t-value formula for r). If would be useful to add it to the computation of effect sizes instead of using imputed correlations.
The drived formula can be found in Appendix B of:

corr = (SD_1^2 + SD_2^2 - (n (x_1 - x_2)^2 / t^2)) / (2 SD_1 * SD_2)
