How Life Science Teams Can Make Evidence Land in the Room
Life science teams invest months generating robust evidence, yet far less attention goes to whether that evidence is read correctly once it reaches a slide. A pie chart can be numerically right and still mislead. A Kaplan-Meier curve can look authoritative and still lose the context that prevents misreading. This report brings together peer-reviewed research and industry benchmarks, and turns them into a practical standard for clinical data slides.
What’s Inside the Report
The Perception Hierarchy
Which chart types audiences actually read accurately, and why pie charts cost precision.
The Kaplan-Meier Problem
Why pasted KM curves get misread, and the three elements that prevent it.
Axis Truncation
Why flagging a truncated axis doesn't stop readers overestimating differences.
Colour & Accessibility
How rainbow heatmaps distort data and exclude colour-blind readers.
The Operational Layer
MLR review cycles, content utilisation and where time is really lost.
A Practical Standard
A 7-point standard for clinical data slides, plus an editor's view from Vaidehi Shukla.
