Figure 7. Tear volume is similar in Muc5ac-deficient mice (KO) compared to wild-type mice (WT).

Figure 7

This is determined by red phenol thread test. Bar graph shows the mean thread measurement in Muc5ac-deficient mice and wild-type. Three measurements (mm) were obtained with the thread placed in the lower lid for 15 seconds with the eyes open. These 3 values were averaged to generate the final measurement, representing the data presented. The mean values from total 31 KO and 15 WT were compared. These two groups were gender and age matched. (NS: Not statistically significant. p = 0.061, independent t-test, error bars indicate 95%CI).
