Exposure-Response Modeling of Monthly Migraine Days for Efficacy of Atogepant in Patients With Episodic or Chronic Migraine.

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
This work aimed to develop an appropriate model to evaluate the exposure-response relationship (ERR) for monthly migraine days (MMD) in atogepant's key migraine prevention clinical trials to support dose selection. The ERR between atogepant concentration and MMD over time was analyzed utilizing data from one phase 2b/3 and three phase 3 studies in patients with episodic or chronic migraine (EM/CM). Several distribution models were evaluated for placebo data, whereas two modified normal distributions were introduced enabling bounded MMD modeling. Exposure metrics and shapes for ERR were tested for the most suitable distribution. Stepwise covariate search, visual predictive checks, and plots of model-predicted MMD over the range of exposure metrics were utilized in model development, evaluation, and selection. The final MMD exposure-response model was able to model patients with EM/CM simultaneously and was based on a modified normal distribution with E
