Proportions of patients reporting that the 29-gauge (29G)/5-bevel needle was better (a 'positive' response), similar (a 'neutral' response) or worse (a 'negative' response) than the 27G/3-bevel needle for questions about pain* and skin penetration(see Table 2 for survey questions). *Questions about pain were asked in all five surveys. Questions about ease of skin penetration were asked in the Australian pilot survey (n = 11) and the US survey (n = 78).
