Results from binomial regressions testing the relationship between time and prevalence rates of six sesamoid bones in the hand

	P‐value	Z‐value	Degrees of freedom
MCP‐I	0.925	0.094	13
MCP‐II	0.400	−0.842	11
MCP‐III	0.855	−0.183	10
MCP‐IV	0.837	−0.205	10
MCP‐V	0.219	−1.229	11
IP‐I	0.363	−0.91	9

Data taken from Table 2 in Yammine (2014). Although Yammine (2014) reported differences in prevalence due to sex and race, all data were pooled here, as there were only 16 studies stretching over 120 years. Prevalence rates were given per hand. In cases where ulnar and radial sesamoid bones were reported separately, the higher value was used, as it was not possible to determine whether the sesamoid bones were always from the same or different individuals. Z‐value = test statistic. A Bonferroni‐corrected P‐value of 0.00833 (P = 0.05/6) shows a lack of any statistically significant trends.
