datasets

Various self-controlled case series models used to investigate
associations between time-varying exposures such as vaccines or
other drugs or non drug exposures and an adverse event can be
fitted. Detailed information on the self-controlled case series
method and its extensions with more examples can be found in

nrtdat function

<p>A data frame containing 141 rows and 7 columns. The column names are 'case' (individual identifier), 'nrt' (age at initiation of NRT treatment), 'mi' (age at first subsequent MI), 'end' (age at end of nominal observation period, nrt + 365), 'act' (age at earliest of end and actual end of observation period), 'cage' (centred age, in years, at NRT), 'cen' (1 if act = end, 0 if act &lt; end).</p>
