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
The coexistence of undernutrition and excess weight is an important child public health challenge. This study described temporal trends and departmental spatial configurations of wasting, stunting, overweight, and obesity among children under five years of age in Peru during 2014-2024. Analyses used anthropometric assessment records from the Nutritional Status Information System (SIEN), collected in public healthcare facilities and aggregated by department and year. Annual Percentage Change summarized average temporal trends, while observed prevalence maps, Global Moran's I, Local Indicators of Spatial Association (LISA), and a median-based bivariate classification were applied independently to 2014, 2019, and 2024. Queen contiguity was the primary spatial specification, along with KNN-4 sensitivity analysis. Wasting and obesity increased on average, stunting decreased, and overweight showed no significant long-term trend. Global autocorrelation was most consistent for wasting, whereas findings for excess-weight indicators were sensitive to the weights matrix. LISA identified local spatial classifications at nominal
