Table 5. Calculation of sensitivity and specificity for probabilistic matching without manual review, not including address variables and using an ETS dataset that only including non-UK born individuals.

Variables used for matching	Sensitivity	Specificity
All with manual review	99.5% (95%CI: 98.9, 99.8)	100.0% (95%CI: 99.9, 100.0)
All without manual review	99.3% (95%CI: 98.7, 99.7)	99.9%(95%CI: 99.8, 100.0)
No address variables (without manual review)	97.1% (95%CI: 95.9, 98.0)	100.0%(95%CI: 99.9, 100.0)
No address variables, only individuals born outside UK (without manual review)	96.5% (95%CI: 94.9, 97.8)	100.0% (95%CI: 99.8, 100.0)
