TL;DR: Bonferroni-based multiple testing procedures (MTPs) are described as strategies to split and recycle test mass, and whenever a null hypothesis is rejected, the part of alpha allocated to it may be recycled to the testing of other hypotheses.

TL;DR: It is shown that Helicobacter pylori infection has been proposed as a protective factor against the development of gastro‐oesophageal reflux disease and is associated with good prognosis in women.

TL;DR: It is concluded that flexible design in its most general form with the corresponding weighted test is not valid and several possible modifications of the flexible design methodology are discussed with a focus on alternative hypothesis tests.

TL;DR: Three different dosages of omeprazole, amoxycillin, and metronidazole were compared, and the influence of metronodazole resistance on eradication was assessed.

TL;DR: This review presents real examples of cardiology trials with different types of non-PH: an early treatment effect, a late treatment effect), and a diminishing treatment effect; the relative merits of a Cox model, an accelerated failure time model, a milestone analysis, and restricted mean survival time are examined.
