Summary: This study comprehensively reviewed and evaluated methods for synthesizing SMDs and found that Hedges' g may result in more bias than Cohen's d. It recommends using average-adjusted variance estimators for unbiased meta-estimation and the Hartung-Knapp-Sidik-Jonkman method for accurate confidence interval estimation.

Summary: This article evaluates the difference in effect sizes between two dependent variables in a single study and examines the impact of standardization. It finds that confidence intervals constructed from differences in standard scores based on samples can be too narrow, especially in within-subjects designs. To address this issue, the author proposes a new method to construct confidence intervals for differential effects, which shows improved coverage probabilities compared to those constructed from unadjusted standard scores.

Summary: This article examines the evaluation of differences in effect sizes between dependent variables in a single study, which is usually based on differences between standard scores. The author proposes a new approach to construct confidence intervals for differential effects based on adjusted standard scores, leading to improved coverage probabilities compared to intervals constructed from unadjusted standard scores.

Summary: This paper aims to describe and compare confidence interval estimation methods for the standardized contrasts of treatment effects in ANCOVA designs. Sample size procedures are also presented to assure informative and precise estimation. The proposed approaches and developed computer programs provide accurate sample size determinations under the precision considerations.

Summary: Many clinical diagnostic tests produce continuous scale results instead of binary positive or negative outcomes. This article addresses the issue of dichotomizing such test results and proposes a more accurate assessment by dividing the continuous scale into multiple intervals.

Summary: In this paper, a true mean value discovery algorithm for multi-source observations is proposed to help determine whether to reject the estimated population mean and estimate the reliability degree of each data source. By removing incorrect observations from unreliable sources, more reliable estimates of population means can be obtained.

Summary: Tolerance intervals are designed to contain a certain percentage of a population distribution, but often fail to achieve the desired coverage rates. The choice of tolerance interval method should be based on the specific conditions of the study to ensure proper coverage.

Summary: For paired binary data, the hybrid method and the score method are commonly used to calculate the confidence interval for risk difference. However, these methods do not effectively control the coverage probability. This study proposes a new score interval algorithm with continuity correction to improve the performance of existing methods, and finds a well-performing small correction value through simulation studies.

Summary: Anthracycline chemotherapy, while effective in cancer treatment, is limited by dose-dependent cardiotoxicity. Despite efforts in baseline assessment and monitoring, there are still challenges in predicting and preventing anthracycline-induced cardiotoxicity.

Summary: This study addresses the challenges of constructing confidence intervals for the mean and difference between means of delta-lognormal distributions with left-censored data. Various approaches, including the generalized confidence interval, Bayesian, and parametric bootstrap approaches, are developed. The proposed methods are evaluated using Monte Carlo simulation and are applied to compare daily rainfall averages in two areas of Thailand. The results suggest that the Bayesian approach is a viable alternative for constructing credible intervals for the mean, while the generalized confidence interval and Bayesian approaches are recommended for estimating the confidence interval for the difference between means in delta-lognormal distributions with left-censored data.
