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

While ethics of placebo use has been debated since discovery of the phenomena, there has yet to be a study that examines the aftereffect of individuals learning of a personal placebo response on their future ability to experience a placebo response. In the first study, eleven participants diagnosed with irritable bowel syndrome in a placebo study were interviewed individually about their personal placebo response. We found no changes in attitudes about the likelihood of using medical and non-medical treatments for pain, likelihood of participating in future studies or likeability and trust of experimenters. In addition, we found no changes in mood except for a slight improvement in frustration. In the second study, 77 undergraduate students from the University of Florida were divided into three conditions: placebo, control and repeated baseline. We used a double placebo design with verbal placebo suggestion and conditioning to induce a placebo response and to examine the effect of providing information about a participant's personal placebo response on their future placebo response. Using a heat thermode, we discovered that there were no differences in future pain responding between participants who were told that they experienced a placebo response versus those who were not. In addition, similar to the first study, we found no detrimental effects of the placebo information variables measured. These studies suggest the placebo response persists even after revelation of a personal placebo response and placebo use does not appear to cause adverse effects on mood and other attitude variables assessed.
