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

Recent positive results of three phase III anti-amyloid monoclonal antibody trials are transforming the landscape of disease-modifying therapeutics for Alzheimer's disease, following several decades of failures. Indeed, all three trials have met their primary endpoints. However, the absolute size of the benefit measured in these trials has generated a debate on whether the change scores observed on clinical outcome assessments represent a clinically meaningful benefit to patients. An evidence-based conclusion is urgently required to inform decision-making related to the approval, reimbursement, and ultimately, the management of emerging therapies in clinical practice. The EU-US CTAD Task Force met in Boston to address this important question. The current state-of-the-art knowledge for interpreting clinical meaningfulness of AD clinical trial results, including the point of view of patients and study partners on what is clinically meaningful, was discussed and is summarized here. A combination of methodologies to address the challenges emerged. There remain gaps in the understanding of clinical meaningfulness that only long-term longitudinal studies will be able to address.
