FR: French dataset; DE: German dataset; ID: number of the event groups (described in Table 3); : number of events; G & R: subset of events in the FR database comprising generic and recurring events; IRS: subset of events reported to the IRS (for FR, only the first-time event for each type is reported); Pr.: precursor events; T5y: trend parameter value (i.e., 0.5 for unchanged number of events, up to 1 for increasing trend, and down to 0 for decreasing trend); U: event groups considered (“Y,” or not “N”) in the presented uncertainty assessment.
