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

backgroundAdvanced glycation end products (AGEs) accumulate in tissues with age and are associated with the risk of chronic diseases. However, evidence regarding lifestyle factors related to AGE accumulation in healthy adolescents is limited. The aim of this study was to explore dietary and lifestyle factors that may attenuate tissue AGE accumulation, using skin autofluorescence (SAF) as a noninvasive proxy marker, in healthy Japanese early adolescent girls.

methodsThis cross-sectional study included 315 first-year junior high school girls aged 12-13 years from a private school in Japan. SAF was measured on the volar forearm using an AGE Reader MU. Dietary intake was assessed using a validated brief diet history questionnaire (BDHQ-15y). Lifestyle factors, including weekday sleep duration, were assessed using a self-administered questionnaire. Health-related variables (including weight-loss dieting) were also collected. Associations between SAF and each factor were analyzed using generalized linear models and nonparametric tests, with multivariable adjustment for potential confounders.

resultsThe mean SAF was 1.06 ± 0.13 arbitrary units. No significant associations were observed between SAF and health-related characteristics, nutrient intakes, or major food-group intakes. Longer weekday sleep duration was significantly associated with lower SAF (

conclusionsIn healthy early adolescent girls, longer weekday sleep duration and better perceived restorative sleep were associated with lower SAF, whereas dietary intake was not. Given the largely irreversible age-related accumulation of AGEs, promoting healthy sleep during adolescence may help attenuate AGE accumulation early in life and reduce long-term AGE-related disease risk. Prospective studies with more detailed dietary assessments are needed to clarify dietary influences and confirm temporality.
