Ligamentum Flavum thickness measurements

<p>This data file contains the data used in the manuscript</p> <p>"Ligamentum Flavum Hypertrophy in Asymptomatic and Chronic Low Back Pain Subjects" by Munns et al. Currently only identified as PONE-D-14-50818.</p

Medial (A) and Lateral (B) ligamentum flavum thickness variation by lumbar level.

<p>Comparison between asymptomatic and chronic low back pain subjects segregated by spinal level. Error bars span one standard deviation. Asterisks denote significant differences with * <i>p</i> < 0.05. In (A) the symptomatic medial thickness tended to be larger than in the normal (L1: p = 0.0839, and L2: p = 0.0652, respectively). All other comparisons did not reach significance.</p

Demographic distribution among asymptomatic and low back pain patients.

<p>Percentages are calculated with respect to the total number of subjects.</p

Ligamentum flavum thicknessby disc grade.

<p>Error bars span one standard deviation. (A) Medial: Asterisks denote significant differences as follows: * <i>p</i> < 0.05; and ** <i>p</i> < 0.001. Medial thickness in grade 3 tended to be larger than that in grade 1 (p = 0.0601). (B) Lateral: Asterisks denote significant differences as follows: * <i>p</i> < 0.05; ** <i>p</i> < 0.01, and *** <i>p</i> < 0.0001. Lateral thickness in grade 2 tended to be larger than that in grade 1 (p = 0.096). All other comparisons did not reach significance.</p
