Abstract

IntroductionTo quantify average angular measurements that define the soft tissue profiles of 12-year-old southern Chinese and to determine gender differences.Materials and methodsA random population sample of 514 12-year-old children was recruited (about 10% of a Hong Kong Chinese birth cohort). Photographs were taken in natural head posture and 12 soft tissue landmarks were located on the photos to measure 12 angular measurements using ImageJ (V1.45s) for Windows. Approximately 10% of photographs were reanalyzed and method error was calculated. Angular norm values for the 12 parameters were determined and gender differences were assessed using 2 sample T-test with 95% confidence interval.ResultsThe response rate was 54.1% (278/514). Norm values for the 12 angular measurements were generated. The greatest variability was found for the nasolabial (Cm-Sn-Ls) and labiomental (Li-Sm-Pg) angles. Gender differences were found in 4 angular parameters: vertical nasal angle (N-Prn/TV)(p¿<¿0.05), cervicomental angle (G-Pg/C-Me)(p¿<¿0.001), facial convexity angle (G-Sn-Pg)(p¿<¿0.01) and total facial convexity angle (G-Prn-Pg)(p¿<¿0.01).ConclusionNorm values for 12 angular measurements among 12-year-old southern Chinese children were provided and some variability noted. Gender differences were apparent in several angular measurements. This study has implications in developing norm values for southern Chinese and for comparison with other ethnic groups.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 19 January 2015.
All research outputs
#3,275,760
of 4,753,611 outputs
Outputs from Head & Face Medicine
#86
of 147 outputs
Outputs of similar age
#109,497
of 159,099 outputs
Outputs of similar age from Head & Face Medicine
#7
of 10 outputs
Altmetric has tracked 4,753,611 research outputs across all sources so far. This one is in the 18th percentile – i.e., 18% of other outputs scored the same or lower than it.
So far Altmetric has tracked 147 research outputs from this source. They receive a mean Attention Score of 1.5. This one is in the 8th percentile – i.e., 8% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 159,099 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 20th percentile – i.e., 20% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 10 others from the same source and published within six weeks on either side of this one. This one has scored higher than 3 of them.
