Table 1 Table to show the mean scores and 95% confidence limits for each of the three variables we measured, sorted by approach

From: A randomised crossover study to compare the cross-sectional and longitudinal approaches to ultrasound-guided peripheral venepuncture in a model

 

Cross-sectional

Longitudinal

Mean no. of skin punctures

1.13 ± 0.19

1.30 ± 0.22

Mean time (seconds)

45.1 ± 15.8

52.8 ± 16.2

Mean difficulty (out of 10)

3.97 ± 0.87

3.93 ± 0.72

  1. The mean score recorded in each box was generated from the 30 individual scores collected for that condition, as each subject attempted each condition once (i.e. n = 30 for each box)
