not quite statistically significantP = 0.071820149
For example, using the NPEST virus with TEVP provided, the average number of remaining “source cells” (defined in this case as cells that were labeled by the virus and expressed both G and TEVP) dropped from 29 at 7 d to 2 at 3 wk [although here again the comparison was not quite statistically significant ( P = 0.071820149) due to the high variance and low number ( 3 ) of mice per group].
