Identification and classification of the interval cases also have an effect on estimation of survival differences between different patient groups.
Compliance differences between different patient groups (eg, prophylaxis versus on-demand, polytherapy versus non-polytherapy, family status, personal life circumstances, etc).
How? Would this differ between different patient groups, for example, related to degree of disease severity, socioeconomic status, age or comorbidity?
Of note, SLE is a highly heterogeneous disease, and it is likely that disease expression may differ between different patient groups, especially regarding major organ involvement, which may have impacted this result.
Matos et al. [ 10] reported that even in the case of equivalent CPR durations, the survival probability still differed greatly between different patient groups.
Furthermore, Matos et al. [ 10] demonstrated that outcomes after paediatric IHCA could differ significantly between different patient groups, indicating that surgical cardiac patients had the highest probability of a good outcome and trauma patients had the lowest probability, and that CPR >20 minutes may not be futile in certain patient groups.
There was no difference between different patients' groups characterised by stage, type of monoclonal protein or light chain.
Numbers of CTC also tended to differ between different patients groups, although this was not statistically significant: no CTC were detected in group A, the median number of CTC in group B was 1 (0–2617) and the median number of CTC in group C was 0.5 (0 153) (P=0.07).
Differences on factor scores between different patients' groups were investigated and pre- and post treatment scores were compared in demonstrating change of perceptions after treatment of fatigue.
The mean WOMAC scores did not differ between the different patient groups; even when BME lesions completely disappeared, lower WOMAC scores were not recorded.
