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

backgroundThe extended time frame of some trials can cause significant challenges in delaying all analyses until the primary outcome is attained. This may particularly affect any mechanistic studies linked to secondary outcomes, as well as impact the involvement of trainees and junior investigators in the project. This manuscript describes the strategy and process by which the leadership of the Healthy Life Trajectories Initiative (HeLTI) developed an analysis approach.

methodsThe study involved the engagement of an expert panel with broad knowledge in disciplines relevant to the study.

resultsSeveral reviewers emphasised the importance of undertaking analysis only after the primary outcome has been achieved. However, the majority of reviewers highlighted that this was not practical in the context of the HeLTI consortium because valuable interim analysis would be missed.

conclusionAfter careful consideration of the issue and feedback received, the HeLTI leadership agreed to an approach that allowed publishing between-group comparisons of secondary outcomes and linked mechanistic studies before the primary outcome, using an a priori agreed phased approach.
