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: Over-the-counter (OTC) medicines are frequently used during pregnancy. As these medicines are often used without medical supervision, accessible and reliable safety information is essential. However, finding reliable and understandable information on the safety of these medicines during pregnancy is often experienced as difficult. Hence, there is a need for a new easily accessible electronic health (eHealth) tool that empowers women to actively seek information to support safer self-medication practices during pregnancy and breastfeeding. Objective: This study aimed to describe the development and dissemination process of a Dutch mobile app providing reliable safety information on OTC medicines during pregnancy and breastfeeding using a development and formative evaluation approach. Methods: The app was developed over a 2-year project comprising 5 phases, including preparation, development, preimplementation, implementation, and evaluation. Mixed-method strategies, including questionnaires, focus groups, and user feedback rounds, were applied to involve the target population in the development process. Medicine safety information in the app was based on the latest scientific evidence. First-year app-usage outcomes included app downloads, usage patterns, and information-seeking behavior. Results: Input from 253 potential users formed the foundation for the development of the MediMama app (Netherlands Pharmacovigilance Centre Lareb), with users expressing a need for clear, reliable, and easily accessible information on medication safety during pregnancy and breastfeeding. The app was launched on Mother's Day 2024 and provides safety information on over 250 OTC medicines, including supplements and herbal remedies, across 27 medicine categories. Promotion occurred through multiple online and offline channels. During its first year, the MediMama app was downloaded 22,415 times, with an average of 370 unique daily users, indicating substantial user engagement. Information on paracetamol (acetaminophen) and nasal sprays was most frequently accessed, reflecting the need for information on commonly used OTC medicines among the target population. Conclusions: One year after its launch, the MediMama app is considered a promising tool in maternity care, meeting the target population's need for accessible OTC medicine safety information. The app aims to support informed decision-making, contributing to safer medication use during pregnancy and breastfeeding. Further research is required to evaluate the effectiveness of the implementation strategy, as well as the app's impact on maternal medication use behaviors and health outcomes.
