50% denoted a follow-up interval or date, and 19% specified the timing of event coded by the previous or following Read term.
As with all routinely collected datasets, errors associated with participant recall (outcomes in relation to the timing of the event), data collection, coding and entry are likely to have occurred, including for the PDC.
Despite the seemingly fortuitous timing of the publication, the revised Code is, quite astoundingly, altogether silent on physicians' duty to care, which might be described as the first among equals of the myriad ethical dilemmas that emerged during the global outbreak.
This has allowed us to examine the performance of the Charlson index in relation to mortality in far more detail than has previously been possible, providing much needed information on its practical use, particularly regarding the timing of included codes to which we found the Charlson index was reassuringly robust.
Industry bias may occur through the choice of comparators, dosing and timing of comparisons, coding of events and selective data analysis, interpretation of data and selective outcome reporting [ 6, 21, 22].
Obtaining the input was a matter of precisely timing in the code used to manipulate the 3 control/data lines.
Numerous studies have shown that brain activity occurs with certain temporal patterns and proposed that the timing of the signals is itself a code (Ahmed and Mehta, 2009; Singer, 2009).
Further, we coded the timing of the post-intervention assessment as the time interval between the end of intervention and the follow-up (in months).
A coded list of the hospitals was produced and a statistician blinded to the coding allocated randomly the timing of the introduction of the intervention to each hospital.
