31.   The results are shown in Table III and the statistical analysis in Table IV.

32.   The results are shown in Table V, and the statistical analysis in Table VI.

33.   This has the advantage of being expressed as a number and is thus amenable to statistical analysis, but it does not recognise different types of colonic pressure waves.

34.   Data are expressed as mean ANOVA, a bilateral paired t test and linear correlation coefficients using X-Y pairs were performed for statistical analysis.

35.   All the statistical analyses were performed with the statistical package BMDP.

36.   Statistical analysis was by paired t test.

37.   Data from these two patients are included in the statistical analysis of the diagnostic anorectal manometry, as they were incontinent.

38.   Statistical analysis of unpaired data was performed using the Mann-Whitney U test and of paired data using the Wilcoxin test.

39.   The fourth patient required local epinephrine injection in addition to repeated heater probe pulses and was considered a failure in the final statistical analysis.
