Study on MEV90 of 0.5% ropivacaine for US-guided caudal epidural block in anorectal surgery
Frontiers in Medicine, 2023 BackgroundChoosing the appropriate concentration and volume of anesthetics is critical for a successful nerve block. The current study aimed to determine the minimum effective volume (MEV) of 0.5% ropivacaine for US-guided CEB in 90% of patients (MEV90 ...

Determination of the 95% effective dose of remimazolam to achieve loss of consciousness during anesthesia induction in different age groups [PDF]
Korean Journal of Anesthesiology, 2022 Background Remimazolam is a new ultra short-acting benzodiazepine originally developed as an improved version of midazolam. Recent studies have demonstrated non-inferiority of remimazolam to propofol in general anesthesia.

The distribution of loss in two-treatment biased-coin designs [PDF]
Biostatistics, 2003 The paper compares randomized rules of the biased-coin type for the sequential allocation of treatments in a clinical trial. An important characteristic is the loss, which measures the increase in the variance of parameter estimates due to the imbalance caused by randomization. Simulations are used to find the small-sample distribution of loss.

Item Selection With Biased-Coin Up-and-Down Designs [PDF]
, 2020 Targeting any arbitrary percentile, the biased-coin up-and-down design is theoretically appealing and can provide an efficient alternative to the current maximum Fisher information method for item selection in adaptive testing. This paper illustrates the

Seamless Clinical Trials with Doubly Adaptive Biased Coin Designs
The New England Journal of Statistics in Data Science, 2023 In addition to scientific questions, clinical trialists often explore or require other design features, such as increasing the power while controlling the type I error rate, minimizing unnecessary exposure to inferior treatments, and comparing multiple treatments in one clinical trial.
