Preregistration of high-quality protocols in pharmacoepidemiology research.
Article in JCPP advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Pharmacoepidemiology studies are an important complement to Randomized Clinical trials, but such studies face several challenges, such as confounding and selective reporting. How to best address confounding has been discussed in detail for many years. More recent discussions have highlighted the value of pharmacoepidemiology studies based on pre-registered protocols. This is an important step to address problems related to selective reporting and to enhance transparency and reproducibility. In this editorial perspective, we discuss the value of pre-registered protocols in pharmacoepidemiology.
