The criteria to classify body-proportionality of the small for gestational age newborn: a scoping review.
Article in BMC pregnancy and childbirth, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTo create an overview of the criteria used to classify small for gestational age (SGA) newborns according to their body-proportionality as either asymmetric SGA or symmetric SGA, and to create an overview of the clinical outcomes related to body-proportionality.
methodsA scoping review was conducted using PubMed, Embase and the Cochrane Library databases. Studies were included if they described SGA newborns regardless of gestational age and if their classification on body-proportionality was given for both aSGA and sSGA. Data were screened and extracted by two independent reviewers.
resultsOf the 38,265 studies identified after deduplication, 45 were included. Body-proportionality was classified by the ponderal index (PI) in 55.6% of studies (n = 25), head circumference (HC) in 24.4% (n = 11), birth length in 11.1% (n = 5), birth length and HC in 4.4% (n = 2), birth length and PI in 2.2% (n = 1), and PI, brain-to-body ratio and HC/length ratio in 2.2% (n = 1). The most commonly reported outcomes were asphyxia, hyperbilirubinemia, hypoglycemia, mortality and respiratory distress syndrome. The results regarding the outcomes were inconsistent and contradictory.
conclusionLarge heterogeneity in the published classifications and clinical outcomes regarding body-proportionality in the SGA newborns exists. Consensus on terms, methods and cut-off values used for body-proportionality is needed to improve future comparison of study results.
