Statistical analysis of continuous outcomes from parallel-arm randomized controlled trials in nutrition-a tutorial.
Article in European journal of clinical nutrition, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 9 papers.
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.
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
Randomized controlled trials (RCTs) play a fundamental role in establishing evidence on benefits of diet changes in nutrition. There is, however, little literature on how to analyze data obtained from such trials. This tutorial provides a detailed introduction to the statistical analysis of parallel-arm RCTs in nutrition by means of modern statistical methodology, i.e., analysis of covariance and linear mixed models are informed using specific information about the trial design. Focus will be on understanding how the trial design and possibly other aspects of the trial influence the subsequent statistical analysis. All steps of the statistical analysis will be covered and a practical example is also provided.
