Rescue effects on relative fitness of defined Δpil mutants in the asocial regimea
| Δpil mutant | Relative fitness

||
|---|---|---|---|
| Rescued Δpil strain (S+) vs. Δpil mutant (S−) | Parent (DK1622, S+) vs. Δpil mutant (S−) | Parent (DK1622, S+) vs. rescued Δpil strain (S+) | |
| ΔpilA | 0.791*** | 0.834** | 1.024*** |
| ΔpilB | 0.856*** | 0.848*** | 1.013ns |

Asterisks indicate statistical significance of the fitness differences between rescued (S+) and unrescued (S−) Δpil mutants and between the parent and unrescued Δpil mutants. The null hypothesis (equal relative fitness) is 1. Significance levels are based on one-tailed t tests in the left and middle fitness columns and two-tailed t tests in the right column. ***, P < 0.001. **, P < 0.01. *, P < 0.05. ns, P > 0.05.
