Brief (2-3 sentences) description of why the study is needed and its contribution to the field.
Background
Dr Laurie Sullivan 2013 [email protected]
Concise (1-2 sentences) statement of the objective or hypothesis to be addressed.
Primary objective identified and stated first, followed by any key secondary objectives.
Objective
Dr Laurie Sullivan 2013 [email protected]
Design: Clear statement of the study's design, including all aspects (eg, parallel group, randomized, blinded). Participants and setting: The most pertinent inclusion
and exclusion criteria, and the setting within which the study was conducted.
Interventions: Complete details on treatment (eg, drug dose, route of administration, and duration of administration) and, if pertinent, control interventions.
Outcome: Primary and secondary outcome measures, identified as such.
Methods
Dr Laurie Sullivan 2013 [email protected]
Conclusions (not summary) of the study, based only on the results shown, with balance of benefits and harms. Clinical application of the findings, again
based only on the data obtained (ie, avoid over-generalization) and whether more study is needed before findings should be implemented into clinical practice.
Conclusions
