A secondary group × time analysis, using slow versus fast subgroups showed significant improvement in the slower group's RCTs post-training (↓ 300 msec, P <.05).
When the ACS-positive group was divided into STEMI and combined NSTEMI/UA cohorts, the modest differences in the closure time in the secondary three-group analysis remained significant (p=0.0001; figure 2C).
Secondary analysis Secondary analysis All secondary analyses have only exploratory character.
Triangulation of findings was carried out: we combined data from different sources (observation notes, focus groups, secondary document analysis).
Modes of data collection included structured interviews using brief questionnaires, semi-structured interviews, direct observation in the field, informal interviews, focus groups, secondary data analysis, and content analysis of media publications.
Given the cross-sectional nature this study and the absence of a control group, the secondary data analysis employed here could not establish a causal relationship between migraine and GERD/heartburn in either direction.
Secondary analysis compared groups of participants with mental health problems and those with muscular skeletal disease separately.
However, although the primary comparison showed no differences in absolute levels of cardiac and blood pressure parameters between groups, the secondary correlation analysis revealed an interesting observation.
A mixed-methods approach was used which included document analysis, key informant interviews, focus-group discussions, secondary data analysis and consensus building by an international dengue expert meeting organised by the World Health Organization, Special Program for Research and Training in Tropical Diseases (WHO-TDR).
For a secondary comparative analysis, the reference group was expanded to comprise all registrants who were not study participants.
