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: To assess the association between early menarche and the nutritional status of the adolescents from the RPS - Brazilian Birth Cohorts Consortium (Ribeirão Preto, Pelotas and São Luís) birth cohort in São Luís, Maranhão. Methods: A longitudinal study with data from the first and third follow-up of the cohort was conducted. A total of 1,225 adolescents aged 18 to 19 years were surveyed and analyzed for age at menarche, defined as early if <12 years old, and for the variable body mass index (BMI) for age, classified into z-scores by sex, as underweight (z-score <-2), adequate weight (z-score ≥-2 and ≤+1), and excess weight (z-score >+1). Directed acyclic graphs were constructed using the DAGitty Results: Out of the 1,225 adolescents investigated, 32.6% experienced early menarche, and the majority had a BMI appropriate for their age (75.2%). Among adolescents with early menarche, 28.3% were classified as excess weight for their age. Multinomial logistic regression revealed an association between early menarche and excess weight (OR = 1.80; 95% CI = 1.21-2.69; p-value = 0.004). Conclusion: Thus, the results indicate an association between the occurrence of early menarche and excess weight in the investigated adolescents.
