  1. Note. P(β 1 > β 2), the probability that β 1 is larger than β 2, measures the strength of the evidence that isolation was associated with reduced transmission (a value of 1 would indicate certainty), and the ratio of β 1 to β 2 measures the relative infectivity of unisolated compared to unisolated patients.
