Table 1.

Contributions of different sources of evidence to PrePPI performance. The second column shows the number of reliable predictions that can be made using only the evidence identified in the first column. The third column shows the number of predictions that can be made without the evidence shown in the first column, but including all other types of evidence. Note that excluding the OR evidence results in more interactions than using all evidence. This is because there are many interactions for which the LR based on orthology is less than 1. Rows with a green background indicate evidence types that use structural information and rows with a blue background evidence types that are based on non-structural information.
