1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Sample size calculations and power analyses are essential components of experimental design in modern biomedical research. Designs that account for sample correlation, multiple testing, and other sources of variability inherent to specific studies are routinely employed for identifying differential expressions. Despite recent advances in methodologies and software tools for power analysis, there remains a lack of statistical packages capable of accommodating these complex designs in differential expression studies. To fill this gap, we provide the R package depower, which implements the simulation-based framework presented in our recent publications. This unified framework covers both independent and dependent group comparisons and controls false positive rates by employing a simulation-based approach to calculate the empirical null distribution of test statistics.
