Inclusion criteria
Inclusion criteria: We will include RCTs published on high-impact journals, which report any SMDs for any continuous outcomes. We restrict the eligible studies to those published on high-impact journals, because we consider that the method used compute the SMD would be better addressed, and results would be more comprehensively provided. Multifactorial RCTs, and crossover RCTs that report results of the first period are eligible.
Exclusion criteria
Exclusion criteria: We will exclude RCTs which use the term "effect size" or "SMD" in a nonspecific way (i.e. sample size calculation), but not for the outcome. We will exclude cluster randomization, quasi-randomized trials, and crossover RCTs whose first period result is not available.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| (1) Study characteristics of RCTs that report SMD; (2) The term and method used to compute the reported SMD; (3) Comparison between reported SMD and SMD which we calculate based on different approaches | — |
Secondary
| Measure | Time frame |
|---|---|
| (1) How RCTs interpret the results in terms of SMD: focusing on whether it is comparable with previous studies (based on same method), and whether it is compared to a standard. (2) Relationship between reporting condition, calculation method and sub-discipline, journal. | — |
