Both purported ancestral islands of each group (Tenerife and Gran Canaria, 12 and 14 Ma, respectively) and the oldest Macaronesian islands (Fuerteventura, 21 Ma) were used as root calibration points; the date of the oldest island (21 Ma) was used as a hard upper bound at the root of each tree.
But I am not so foolish as to predict from these data points the date when I will break the world record (or the speed of sound, or light, for that matter).
Person-years of follow-up were counted from the date of the baseline survey until one of the following end points: the date of emigration from Japan, the date of death or the end of the study period (31 December 2010), whichever comes first.
As precise dates (in millions of years) are not available for these calibration points, the dates used are the most recent dates associated with the geological time intervals from which the fossils were collected.
GetOrganizations retrieves the list of organizations that are currently registered as data providers along with service end point, the date of the most recent data harvest, when the server was last pinged, and an indication of whether the endpoint is available.
For survival analyses, we considered the baseline time-point the date of the first TE examination in which the diagnosis of cirrhosis was established.
For the incident group the diagnosis was validated at 'the incident time point', the date of the first visits listing a diagnosis code for RA.
Similarly, when the divergence time between human and armadillo (96.2 Mya) was used as a reference point, the date of the duplication event giving rise to the armadillo trappin gene family was calculated as 15.5 Mya.
Using the tablet computer's built-in camera function, we scanned barcodes at the time of vaccination, registered the vaccinee in the database at which point the date, dose, and batch number were recorded.
For instance, when the divergence time between sheep and cow (18.3 Mya) was used as a calibration point, the date of the duplication events giving rise to the pig and bovine trappin gene families were calculated as 7.8 and 9.7 Mya, respectively.
When the divergence time between Primate and Artiodactyla (96.2 Mya) was used as a reference point, the date of the duplications of trappin genes of pig, cow, armadillo, guinea pig, and Afrotheria (elephant, hyrax, and tenrec) were calculated as 7.0, 8.8, 15.9, 79.0, and 161 Mya, respectively (asterisks in Figure 3).
