Table 3 Surgical outcome – comparison between consultants and residents. This table provides detailed information on the statistical evaluation of the surgical outcome between consultants and residents. Surgical outcome was evaluated by comparing the stone-free rate, the rate of reintervention and the rate of complications between residents and consultants. For each event (stone-free rate, rate of reintervention, rate of complication) and each group (consultants and residents) the number of patients (n) meeting the criteria as well as their percentage in relation to the total number of patients for each group, are given. Differences between both groups (residents and consultants) on each event (stone-free rate, rate of reintervention, rate of complication) were calculated using Fisher’s exact test. The odd’s ratio was calculated to evaluate the tests’ effect size. For each event the p-value and the odds ratio for both groups (residents and consultants) are given.
