When analysing data from randomised clinical trials, intention-to-treat analysis provides the highest level of evidence.
Variables were analyzed in accordance with the CONSORT statement for randomized controlled trials intention-to-treat principle; that is, dropouts from the two-week training were invited to participate in the error assessment to avoid selection bias.
Data analyses were conducted on the enrolled subjects who met eligibility criteria for participation in the trial (intention-to-treat analysis).
The current study, a 10-year, within-trial, intention-to-treat analysis of the DPP/DPPOS demonstrates that lifestyle is indeed cost-effective, and metformin is marginally cost-saving or at least cost-neutral compared with placebo.
This 10-year, within trial, intention-to-treat economic analysis of the DPP/DPPOS demonstrates that lifestyle, when compared with placebo, is cost-effective, and metformin is marginally cost-saving from a health system and societal perspective.
cIAIs: complicated intra-abdominal infections; APIs: acute pelvic infections; cSSSIs: complicated skin and skin-structure infections; RCTs: randomized controlled trials; ITT: intention to treat; MITT: modified intention to treat; TOC: test-of-cure; FEM: fixed-effect model; REM: random-effects model; OR: odds ratios; CI: confidence intervals.
High quality trial design, with intention-to-analysis, adequate follow-up and baseline similarity, would advance the quality of work in this field.
2) double blinded trials with intention to treat analysis.
These behavioral findings confirm the existence of different neural processes between new and repeated trials during intention understanding.
In all, 13 (65%) trials performed intention to treat (ITT) analyses (see Supplementary material).
11 12 13 Guidelines now recommend that randomised controlled trials use intention to treat analysis.
