Schwartz MD• There is no significant difference between TcB measurements of the sternum compared with those of the lower abdomen, under the diaper• TcB measurements of the sternum correlate positively to those taken on the lower abdomen with a correlation coefficient of 0.954• The strong correlation coupled with the small standard deviation and mean indicate that the lower abdomen could be a useful location for TcB measurement• Determine the relationship between transcutaneous bilirubin measurements of the standard sternal location and those taken from the lower abdomen, covered by the diaperINTRODUCTION RESULTS CONCLUSIONSOBJECTIVEFUTURE DIRECTIONSMETHODSMeasurements recorded on paper log without any patient or clinical informationClinical measurements taken in outpatient setting using JM-105Statistical analysis performed using linear regression calculatorFigure 1: Sternal Measurements vs. Abdominal Measurements• The slope (m) of the linear regression plot, 0.939, the high r value, 0.954 , and the high R² value of about 0.910 combined with the small y-intercept shows that there is no significant difference in the bilirubin measurement at the two locationsTable 1: Linear Regression InformationSample Size (n): 48Slope (m) 0.969Regression Equation: y = 0.939x+ 0.604Correlation Coefficient (r): 0.954• Standard deviation of absolute difference: 0.530• Mean of absolute difference: 0.762• Further study is needed to assess whether TcB measurement in the diaper area correlates with serum bilirubin during and after phototherapy• Future studies should be conducted to further confirm or refute our findingsReferences:1.
