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

objectivesTo assess views of parents of babies who participated in a neonatal trial, about feedback of trial results.

designQualitative analysis of interviews.

settingParents' homes. SUBJECTS: Parents of 24 surviving babies enrolled in a UK randomised controlled trial comparing ventilatory support by extracorporeal membrane oxygenation with conventional management.

main outcome measuresViews about contents of results, reactions to results, effect of hindsight, and importance of feedback.

resultsInformation about mortality was well understood by the parents but morbidity was less clearly reported. Even when the content was emotionally exacting, the information was still wanted as it removed uncertainty; provided an endpoint to difficult events; promoted further discussion within couples; and acknowledged their contribution to answering an important clinical question.

conclusionsFeedback of trial results to participants should be a consideration of researchers, but a careful approach is required. This study was based on a highly selective group of parents within a particularly sensitive trial. More research is needed to assess the extent to which these results can be generalised to other trials or to groups such as bereaved parents.
