Adaptations and Heterogeneity of Treatment Effects in Platform Trials-Protocol for Two Methodological Studies.
Article in Acta anaesthesiologica Scandinavica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAdaptive platform trials bring opportunities for improved infrastructure and effective advancement in medical care but are methodologically complex. Assessment of heterogeneity of treatment effects (HTE) according to participant characteristics and adaptations, including adaptive stopping, are important methodological features in these trials, which may be approached in multiple ways. We aim to characterise the assessment of HTE and use of adaptations, including their key methodological features, in adaptive platform trials.
methodsThis protocol outlines two methodological studies, which will be based on a common, systematic literature search and data extraction. We will include adaptive platform trials conducted from 2005 onwards. Screening and data extraction will be performed independently and in duplicate. In Study I, we will assess methods used to evaluate HTE, and in Study II, we will assess adaptations and stopping rules in the included trials. DISCUSSION: The two proposed methodological studies will provide an overview of important methodological features regarding the assessment of HTE and adaptations used in adaptive platform trials. Better knowledge of available methods to assess these features can improve the conditions for designing adaptive platform trials and identify areas for further development.
