However, 13.0% of PPP wall are in poor condition, and 80.1% of walls are only fair, comparisons of the condition of housing elements in the three strategies revealed that all the parameters of houses were found to have significant differences with p values reported for the comparison were observed to be less than 0.05 confidence level (p < 0.05).
