Nocebo effect in inhaler use: Patients' beliefs and treatment adherence.
Article in Exploratory research in clinical and social pharmacy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Background: The nocebo effect refers to the experience of nonspecific symptoms attributed to medical treatments, which cannot be explained by the pharmacological effects of the medication. This phenomenon, where symptoms are incorrectly linked to a treatment, can have significant implications for treatment adherence and may lead to increased patient demand for medical assistance. Objective: To ascertain the frequency and types of nocebo effects attributed to inhaler use, along with the associated factors. Methods: An interview was conducted to inquire about adverse effects attributed to inhalers. Additionally, questionnaires on beliefs about medications, general and specific to inhalers, and perceived sensitivity to medications scale were administered. Adherence to inhaled therapy was established using the inhaler adherence test and the electronic prescription refill rate at the pharmacy. Results: A total of 134 patients were included, among whom 21 (16 %) attributed symptoms to inhalers that were considered to be due to the nocebo effect. Patients experiencing nocebo-related symptoms exhibited greater concerns about using inhalers, heightened sensitivity to drug effects, and lower therapeutic adherence. Conclusions: A significant proportion of patients receiving inhaler therapy associate negative symptoms that are not reasonably attributable to the inhalers themselves. Patients prone to attributing nonspecific symptoms to inhalers differ in their beliefs about medications and exhibit lower therapeutic adherence compared to others.
