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

backgroundStudies recommend randomising the order of attributes in discrete choice experiments (DCEs) to avoid bias; however, in a benefit-risk setting, this may increase the cognitive burden of respondents who compare the benefits and risks of treatments, or may affect their decision-making process. Based on these concerns, this paper explored attribute ordering effects in a benefit-risk DCE.

methodAttribute ordering effects were explored in a large pilot DCE relating to the medical treatment of insomnia. Participants were randomised to one of three presentation orders: (1) benefits were presented before risks (BR); (2) risks were presented before benefits (RB); (3) all attributes were randomised (RN). For the RB and BR presentation orders, attributes were randomised within benefits and risks. Responses were assessed in three ways. First, variations in respondents' self-reported choice certainty were obtained. Second, variations in failure rates of stability and dominance tests were calculated. Third, a heteroscedastic error component model tested for differences in choice consistency across the three attribute orderings.

resultsThe final analysis included 156 respondents (RN: 54; BR: 49; RB: 53). No differences were found between the presentation orders with respect to stated choice certainty, or the proportion of respondents failing either the dominance or stability test. However, deterministic attribute grouping was associated with higher choice consistency.

conclusionTo increase choice consistency, DCE attributes should be randomised within logical groups that may be further randomised to reduce the risk of ordering effects.
