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

introductionClimate change is silently reshaping childhood, especially in the world's most vulnerable regions. This scoping review explores how environmental stressors-such as rising temperatures, altered rainfall patterns, droughts, and floods-affect the nutritional status of children under 5 years of age.

methodsA systematic search of four major databases yielded 1586 studies, of which 37 met the inclusion criteria.

resultsOur findings reveal that climate change impacts child malnutrition primarily through indirect pathways influenced by food insecurity, disruptions in agricultural production, and deep-rooted socioeconomic inequalities. Stunting emerged as the most frequently and severely affected outcome, while overweight and obesity were rarely addressed-highlighting important gaps in the current evidence. Socioeconomic factors such as caregiver education, rural residence, and household income were consistently identified as key variables, shaping the extent to which climate risks translate into nutritional harm. Most studies focused on countries in Sub-Saharan Africa and South Asia, where the burden of vulnerability is greatest. Beyond documenting associations, this review draws attention to a broader reality: that child nutrition today is threatened not by a single crisis but by a web of interconnected challenges.

conclusionAs the global polycrisis unfolds, early childhood nutrition demands urgent, coordinated responses that are evidence-based, socially just, and future-oriented.
