Figure 4. Percentage distribution of silver deposits within the hybrid layers of specimens aged in different media for up to 12 mos. Both modes of silver deposition in the hybrid layers are included, since we could not distinguish between the reticular patterns and the isolated silver grains during image analyses. Groups identified by different letter are significantly different (p < 0.05). M, month. In box plots, the distance between the upper and lower brackets includes 80% of the values. The box includes 50% of the values. The horizontal line in the box represents the median.
