. xtunitroot fisher D.lnfdi,dfuller drift lags(1) demean

Fisher-type unit-root test for D.lnfdi
Based on augmented Dickey-Fuller tests
--------------------------------------
Ho: All panels contain unit roots           Number of panels  =      5
Ha: At least one panel is stationary        Number of periods =      9

AR parameter: Panel-specific                Asymptotics: T -> Infinity
Panel means:  Included
Time trend:   Not included                  Cross-sectional means removed
Drift term:   Included                      ADF regressions: 1 lag

                                  Statistic      p-value
------------------------------------------------------------------------------
Inverse chi-squared(10)   P        32.0481       0.0004
Inverse normal            Z        -3.7439       0.0001
Inverse logit t(29)       L*       -3.9216       0.0002
Modified inv. chi-squared Pm        4.9301       0.0000
------------------------------------------------------------------------------
P statistic requires number of panels to be finite.
Other statistics are suitable for finite or infinite number of panels.

请问检验结果该如何看呀？P，Z ，L* ，Pm应该看哪个？并且，这个Fisher检验的时候，输入 xtunitroot fisher D.lnfdi,dfuller drift lags(1) demean中的drift和trend怎么理解？因为如果输入的是trend，，这个值都比较大，求助！万分感谢！
