Table 2 Anal manometric parameters of the two patient groups and control group

Anal manometric parameters	OD with ED group (n = 32 patients) mean ± SD	OD without ED group (n = 33 patients) mean ± SD	Control group (n = 15 subjects) mean ± SD	Test of significance	P
Maximum squeezing anal pressure (hPa)	67.75 ± 19.75^†	70.24 ± 26.17^\|\|	101.93 ± 18.23^†^\|\|	K = 19.990	≤ 0.0001*
Maximum straining anal pressure (hPa)	57.93 ± 13.34^‡^§	40.48 ± 14.98^‡¶	0 ± 0^§¶	K = 48.069	≤ 0.0001*

hPa, hectopascal (it is the unit of pressure and it is equal to 100 Pascals); OD, obstructed defecation; ED, erectile dysfunction; n, number of subjects; SD, standard deviation; K, value of Kruskel-Wallis test; Z, value of Mann Whitney test
*P is significant at < 0.05
