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

	P‐value	Z‐value	Degrees of freedom
MTP‐II	0.939	−0.077	14
MTP‐III	0.101	0.920	14
MTP‐IV	0.937	−0.079	14
MTP‐V	0.986	−0.017	14

Data taken from Table 6 in Yammine (2015): data on the hallux (Table 2) were not analysed because they were highly mixed. Similar to the data with the sesamoid bones in the data, all data were pooled here, as there were only 16 studies stretching over 121 years. Prevalence rates were given per foot. In cases where tibial and ulnar sesamoid bones were reported separately, the higher value was used, as it was not possible to determine if the sesamoid bones were always from the same or different individuals. Z‐value = test statistic. A Bonferroni‐corrected P‐value of 0.0125 (P = 0.05/4) shows a lack of any statistically significant trends.
