Clinician Measurement Meta-Analysis Visualizer Biostatistical Engine

Clinician-measured studies (e.g., Veale et al. meta-analysis, N=15,521) establish a standardized biological mean of 13.12 cm (5.16 in) with a standard deviation of 1.66 cm. Unsupervised self-reported survey methodologies exhibit a persistent upward bias shift of +1.88 cm (+0.74 in) due to sampling distortion and social desirability bias.
