Normative data for stretched penile length in term neonates born in Tamil Nadu
Open accessAbstract
Aim: To establish normative data for stretched penile length (SPL) in term male neonates born in Tamil Nadu. Materials and Methods: All live term male neonates delivered in a hospital during a given period were included. SPL was measured from the pubic ramus to the tip of the glans. Two consecutive measurements were taken and average was recorded. Results: The mean SPL observed in our study was 2.83 ± 0.49 cm. Conclusion: This study helps establish normative values for SPL in neonates of Tamil Nadu origin.

Differences in absolute values have been attributed to ethnicity, age distribution, and measurement techniques.
“Differences in absolute values have been attributed to ethnicity age distribution and measurement techniques [7, 8, 19, 20].”

The Introduction and Discussion attribute differences in penile length to race or ethnicity, and the Discussion suggests that sample size and observational variation may explain a difference between studies. The paper does not attribute differences in absolute values to age distribution, and its description of how length was measured does not establish differences in measurement techniques as an explanation. (LLM, conf=0.86)
Experimental — accuracy not yet measuredIn neighboring India, many studies have been conducted to establish local nomograms for pediatric male external genitalia, some representing statewise populations.
“Pakistan lacks the sufficient reference data for this purpose, while on the other hand, in neighboring India, which shares close ethnic proximity, many studies have been conducted only for this sole purpose, some of which represent the statewise population highlighting the importance of locally derived nomograms [8, 15-19].”

“Measurement of SPL helps to identify micropenis in the neonatal period (usually defined as lesser than 2 standard deviations (SDs) for that ethnicity) that may signify serious underlying endocrinopathy.[6,7] The phallic growth in utero and early infancy is dependent on androgens and growth hormone.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
