Elevated Fall-Related Mortality Rates New Mexico, 19992004 Aaron M. Wendelboe, PhD New Mexico Department of Health OWCD, CDD, EIS Field Assignments Branch Background (1-2 min) Usually a few slides
Engage audience Set stage for outbreak investigation Provide rationale for planned study Essential information (only) about project Establish relevance to health Include a slide describing study objectives Methods (1-2 min) Usually a few slides Describe study design(s)
Tell how controls were selected if CC study Define cohort if cohort study Say what laboratory tests were used Results (3-4 min) Usually several slides Emphasize most important findings Describe characteristics of study participants Include descriptive results and analytic
results Use mixture of text, tables, figures, photos as appropriate to your data Discussion (2-3 min) Interpretation of findings
Dont repeat results Prioritize findings from most to least important Link findings to study objectives Put findings into context with previous studies Limitations slide (only the important ones) Conclusions slide(s) based on your findings Recommendations slide(s) Control measures
Directions for future studies Acknowledgments (10-15 sec) Recognize coauthors and contributors Same logos as on title slide Your last words = Thank You Creating Effective Slides Effective Slides
Are uncluttered, clear, visible Dont distract the audience Use informative titles Characteristics of Study Participants Risk Factors for Illness Not Results 1, Results 2 Use bolded, sans serif font (Arial, Tahoma) Have simple, high-contrast, consistent color schemes
Color-Blind Friendly Presentations Avoid red-green color combinations If must use red, use yellowish red (R=255 / G=82 / B=0) instead of pure red Avoid red characters / lines on dark background Make text and lines as big or thick as practical Use high-contrast color scheme Recommended Fonts and Sizes
Sans serif font, all titles and text bolded For Arial (bolded): Titles 36 pt Main bullets 28 pt Sub-bullets 28 pt if room, otherwise 24 pt Avoid sub-sub bullets (re-format) Keep text / title size consistent across slides Stop PowerPoint from changing text size as you type Go to Tools, AutoCorrect
Uncheck Autofit body/title text to placeholder Effective Text Slides Order of slide text matches order of script Key words only, not complete sentences 810 lines maximum Bulleted text better than numbered items in most cases Parallel structure (all verbs, all nouns, etc)
Things to Avoid Visual clutter from too many colors Unbolded, serif font like Times New Roman ALL CAPS (HARD ON THE EYES) Pseudo-3D charts and graphs Animation (no flying objects; slide builds=OK) Clip art that serves no purpose Unnecessary grid lines in figures Necessary lines that are too thin All PowerPoint design templates
Photos and Clip Art Tips Should serve a purpose No copyrighted materials without permission No photos of identifiable people unless release No photos of your kids or your pets Clip art cautions Simplest is most effective Check in Slide Show to make sure it is not animated
Tips on Delivering Oral Presentations Preparation Tips Use script, flesh out bullet pts into sentences Practice is the key to making sure it doesnt sound scripted Print your script in large enough type (14-16 pt) Check script size in Notes Master or Notes view
Print one slide and accompanying script per page Time your presentation If you used Rehearse slide timings feature, go to Slide Show, Set Up Show, and uncheck Advance slides using timings if present Delivery Tips
Get there early
Dont start speaking until ready Speak slowly and with sufficient volume Dont turn your back on your audience Check that the correct slide is projecting Use microphone correctly Be careful with humor Explain charts / graphs before giving point Explain associations clearly Pause before advancing to next slide
Reasons Not to Use a Laser Pointer Have to turn away from audience to use it Some projection screens absorb the laser, so audience in room cannot see it Color-blind people cant see it (red) Can become a crutch If your hands are shaking, pointer will show it Alternatives: Building pointers into slides Using computer cursor (arrow)
Question & Answer Period: Donts Dont fumble for extra slides Dont be defensive even if question hostile Dont ask Did that answer your question? Dont thank the questioner for the question Dont rate the question Dont back away from the podium as if poison Dont hang on to podium as if life-preserver
Take-Home Messages Decide type of data and the point you want to convey, then choose the visual accordingly (text, table, graph, chart, etc.) Well organized, practiced presentation with clear, effective slides (when used) reinforces your message and helps you communicate effectively Good science is more important than glitz
