Examining the estimate of the slope of the linear relationship between the response and von Frey filament for von Frey Test 2 revealed the absence of an oestrus cycle effect across all surgery groups.

Results are expressed as the percent difference in slope between the response and two von Frey filaments, generated from response rates (the percent response /30 across von Frey filaments; Table A3). A t-value of < −2 or >2 was determined statistically significant (p < 0.05) when difference in percentage response were greater than 3.3%. n = 8 per treatment group, per sex. n = 8 per oestrus phase. N, number of sciatic sutures; S, number of subcutaneous sutures; g, grams force. Di, dioestrus; Met, metoestrus; Oest, oestrus; Pro, pro-oestrus. %, the average difference in percent response; t =, is there a significant effect of oestrus cycle?
