Data were extracted by a single author (AJA) using a proforma and included information on region, study dates, study population, duration of fistula, type of fistula, risk factors, associated complications and denominators, how fistula were ascertained, sampling technique, number of women and number of deliveries.
Previous studies have reported relations between indices of response monitoring and repetition in OCD (Gehring et al., 2000; Ursu et al., 2003) and in non-clinically ascertained samples of children and adults with obsessive compulsive characteristics (Hajcak and Simons, 2002; Santesso et al., 2006).
Among 1751, distinct haplogroup status was ascertained for 654 samples, where as 1097 samples remained as M* samples.
KDA ascertained the patient samples and their clinical information.
The use of a well characterized, epidemiologically ascertained sample with detailed demographic and psychosocial assessments allowed for well-matched samples in terms of age, gender, and handedness.
In order to ascertain sample representativeness of sample from the population surveyed.
