In this small pilot study , the devices were similar in glucose excursion ( median [ quartile 1 , quartile 3 ] , InsuJet vs. FlexPen , 9.4 [ 4.8 , 12.8 ] vs. 8.1 [ 5.4 , 10.6 ] mmol/L ; P = 0.43 ) , in the area under the glucose concentration-time curve for 0-240 min corrected for baseline glucose level ( InsuJet vs. FlexPen , 1,230 [ 623 , 2,012 ] vs. 1,175 [ 91 , 1,774 ] mmol min/L ; P = 0.4 ) , and in insulin absorption over the 240-min period .
