Tanner's target height formula underestimates final adult height in Korean adolescents and young adults: reassessment of target height based on the Korean National Health and Nutrition Examination Survey 2010-2019.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveEstimating children's target height (TH) plays an important role in diagnosing, evaluating and treating many paediatric endocrinological diseases. However, in many countries, employing Tanner's formula to predict children's final adult height (FAH) is considered misleading. Therefore, this study aimed to re-evaluate the validity of Tanner's formula for predicting the TH of Korean adolescents and young adults and develop a new formula suitable for Korean children. DESIGN/
settingData were derived from the Korean National Health and Nutrition Examination Survey 2010-2019. PATIENTS: A total of 2586 participants (1266 men, 1320 women) were included, excluding participants for whom Tanner's formula could not be calculated because of missing parental height data.
main outcome measuresTanner-based TH was compared with the FAH.
resultsThe difference between Tanner-based TH and FAH was 4.86±0.178 cm for men and 4.81±0.150 cm for women. Sex-specific univariable and multivariable analyses were conducted to determine variables influencing positive height gap (greater than estimated TH). Both men and women with higher education levels were more likely to exhibit a positive height gap. Those with a history of chronic illness were less likely to exhibit a positive height gap, particularly in women. Using a new formula derived using linear regression analysis, the sum of parental heights explained 27.6% and 30.6% of the variance in sons' and daughters' heights, respectively.
conclusionsTanner's formula for calculating TH tended to underestimate FAH; hence, our new formula may offer a better alternative for estimating TH and evaluating growth in Korean children and adolescents.
