Summary
Researchers often do not share data even when stating they will in data availability statements (DAS). This suggests mandatory DAS alone may not ensure data sharing for open-access publications.
Area of Science:
- Bibliometrics
- Scholarly Communication
- Open Science
Background:
- Open-access publishing mandates data availability statements (DAS).
- Ensuring researchers comply with DAS is crucial for scientific transparency and reproducibility.
Purpose of the Study:
- To assess researcher compliance with data availability statements.
- To determine the effectiveness of mandatory DAS in facilitating data sharing.
Main Methods:
- Analysis of 3556 articles from 333 open-access journals published in January 2019.
- Categorization of DAS types and survey of corresponding authors.
- Attempted reanalysis of shared data sets.
Main Results:
- 3416 out of 3556 articles contained a DAS.
- 42% of DAS indicated data availability upon reasonable request.
- 93% of authors who stated data would be shared did not respond or declined; only 6.8% provided data.
Conclusions:
- Researcher compliance with data availability statements is low.
- Mandatory DAS may not be sufficient to guarantee actual data sharing.
- Further strategies are needed to improve data sharing practices in open-access research.

01:15Systematic Error: Methodological and Sampling Errors
2.7K
In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

01:07Data Collection by Survey
7.2K
The systematic method of obtaining and analyzing accurate information of a population is called data collection. A survey is a standard method of data collection that involves collecting information from a target human population about their experience, opinion, or knowledge of a product, service, or process. The responses are recorded and interpreted. The most common survey examples are written questionnaires, face-to-face or telephonic conversations, focus groups, and electronic (e-mail or...
