Summary
Making cancer microarray clinical trial data publicly available significantly increases citations. This finding encourages researchers to share their data, boosting scientific impact and discoverability.
Area of Science:
- Biomedical research
- Genomics
- Clinical trials
Background:
- Sharing research data benefits the scientific community.
- The direct benefits for individual investigators sharing data are less apparent.
Purpose of the Study:
- To investigate the impact of publicly available microarray data on the citation rates of cancer clinical trial publications.
Main Methods:
- Analysis of citation history for 85 cancer microarray clinical trial publications.
- Statistical analysis using linear regression to assess the association between data availability and citations, controlling for confounding factors.
Main Results:
- 48% of trials had publicly available microarray data, receiving 85% of total citations.
- Publicly available data was significantly associated with a 69% increase in citations (p = 0.006).
- This association remained significant after adjusting for journal impact factor, publication date, and author country.
Conclusions:
- A strong correlation exists between the public availability of research data and increased literature impact.
- This correlation may serve as a significant motivator for researchers to share their detailed research data.

02:46Chi-square Analysis
The chi-square test is a statistical hypothesis test. It is used to check whether there is a significant difference between an expected value and an observed value. In the context of genetics, it enables us to either accept or reject a hypothesis, based on how much the observed values deviate from the expected values.
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...

01:15Study Design in Statistics
A study design is a set of techniques that allow a researcher to collect and analyze data from different variables defined for a specific research problem. Statistics is commonly for effective study design and more robust experiments,

01:56Ethics in Research
Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.
01:13Data Collection by Experiments
Data collection is a systematic method of obtaining, observing, measuring, and analyzing accurate information. An experimental study is a standard method of data collection that involves the manipulation of the samples by applying some form of treatment prior to data collection. It refers to manipulating one variable to determine its changes on another variable. The sample subjected to treatment is known as “experimental units.”

01:40Archival Research
Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...
01:07Data Collection by Survey
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...
