Figure 3From: Publication trends of shared decision making in 15 high impact medical journals: a full-text review with bibliometric analysis Relative numbers of SDM publications over time. The curve was estimated in a Poisson model; with the percentage of SDM publications over the total of the year as a dependent variable (100 ∗ N/Total) and year since 1996 as an independent variable (t). 100 ∗ N/Total = 100 ∗ exp(-5.92 + 0.16 ∗ t - 0.02 ∗ t2 + 0.0008 ∗ t3). All coefficients P < 0.05, except for t2 coefficient P < 0.10.Back to article page
