| Vegetation Type | Mean Difference | 95% Confidence Interval | P Value |
|---|---|---|---|
| Pure vegetation | |||
| CG Vs EC | 4.15 | 0.65–7.65 | .010 |
| CG vs EF | 2.03 | 0.69–3.37 | <.001 |
| EC vs EF | −2.17 | −5.50–1.27 | .474 |
| Mixed vegetation | |||
| ECCG vs EFCG | −1.91 | −5.70–1.96 | .722 |
| ECCG vs EFEC | 2.80 | −1.63–7.23 | .464 |
| EFCG vs EFEC | 4.71 | 1.14–8.27 | .002 |
Mean differences in the distributions of Biomphalaria snails according to pure vegetation and mixed vegetation were determined using Tukey's post hoc test.
