Primary Institution: University of Wisconsin-Milwaukee

Hypothesis

Are other associated texts important for understanding the meaning of figures in biomedical articles?

Conclusion

Associated text beyond the figure legend is crucial for biomedical scientists to fully understand figures in research articles.

Supporting Evidence

  • Figure comprehension increased significantly with more associated text.
  • Biomedical researchers missed 39-68% of information with only figure legends.
  • Full-text access improved figure comprehension to 86-97%.

Takeaway

Scientists need more than just figure captions to understand research figures; they also need titles, abstracts, and full texts.

Methodology

Twenty subjects evaluated three figure-text combinations using a Likert scale to assess comprehension.

Potential Biases

Potential bias due to the sequential evaluation of figure-text combinations.

Limitations

The study design may introduce bias as subjects were exposed to figures incrementally.

Participant Demographics

Subjects were bench biomedical scientists, including PhD candidates and post-docs.
