1 · What the graph read from it

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.

2 · The registry

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

Objective: Turkish growth reference charts are based on 1989-2002 data. Globally, positive secular trends in height have been observed, and updating growth charts every 20 years is recommended. Additionally, obesity is a rising health issue worldwide. This study investigates if there has been a further increase in young Turkish adults’ mean height and body mass index (BMI) compared to previous national data (TK2002) and Turkish-origin young adults in the Netherlands. It also explores the association between adult height and BMI with socioeconomic status (SES) and geographical region. Methods: This cross-sectional study (2023-2024) included 217 females and 248 males, aged 18-26, voluntarily recruited randomly selected from İstanbul University, representing all regions of Türkiye. Height, weight, and SES were recorded. The top two SES groups were combined for analysis. Results: Sample distribution aligned with Türkiye’s regional population distribution. Mean height was 1.8 cm taller in females (p=0.003) and males (p<0.001) compared to TK2002, and also taller (2.3 and 0.5 cm, respectively, p<0.001 and p=0.03) than in Netherlands measured in 2009 (NL2009). BMI was significantly higher in males than in TK2002 and NL2009 (p<0.001). Conclusion: Final height of Turkish students increased by 1.8 cm in both sexes over two decades. Males’ BMI was alarmingly high (58% overweight or obese). A population growth study to generate updated growth charts from birth to young adulthood and prevention programs to reduce obesity are needed.
