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

The goal of this article is to demonstrate the importance of pilot studies in empirical eye-tracking research. First, we show what can go wrong when proper pilot experiments are omitted for all phases of an eye-tracking study, from testing an experiment, conducting the data collection, to building, revising, and interpreting the data analysis. Second, we describe a series of eye-tracking studies as a case study, and elaborate on all the pilot experiments that were conducted. We highlight what was learned from each pilot experiment when conceiving, designing, and conducting the research. Finally, we give practical advice for eye-tracking researchers on planning and conducting pilot experiments. This advice can be summarized as (1) take enough time, (2) be problem-oriented, (3) pilots are of an iterative nature, (4) many questions are empirical, and (5) apply the four-eyes principle. We envision that the present article helps early career researchers discover, and more established researchers rediscover, the utility of pilot experiments.
