Crowd-figure-pictograms improve women's knowledge about mammography screening: results from a randomised controlled trial.

ABSTRACT:

Objective

To evaluate the effect of crowd-figure-pictograms on women's numeric knowledge about mammography screening in a three-armed parallel randomised controlled trial.

Results

552 women were randomised to receive (1) non-numeric information (n = 192), (2) non-numeric and numeric information (n = 186), or (3) non-numeric and numeric information complemented by crowd-figure-pictograms (n = 174). Baseline numeric knowledge was low (control 0.61, numeric 0.66, and pictogram 0.51 on a scale ranging from 0 to 5). Women in the crowd-figure-pictogram group had a larger knowledge increase than women in the numeric group (2.42 vs 2.06, p = .03). Both groups had significant increases in knowledge compared to the control (0.20, p < .001). Providing numeric information in absolute nu
