Early-Life Feeding Behavior and Sensory Processing in Autism Spectrum Disorder: A Systematic Review and Meta-Analysis.
Article in Journal of autism and developmental disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeAutism Spectrum Disorder (ASD) affects around 2.8% of the population, yet early diagnosis remains challenging and may delay beneficial interventions. Atypical sensory processing and feeding difficulties are frequently reported in ASD and have been discussed as early behavioral correlates. We conducted a systematic review and meta-analysis to examine associations between these features and to delineate behavioral patterns that may support early developmental assessment.
methodsStudies published until November 15, 2023, were included if they assessed feeding behavior alongside sensory processing or multisensory integration. Articles without original data were excluded. Risk of bias was evaluated using the QUIPS tool, and the protocol was registered in PROSPERO (CRD42023483136). We searched PubMed, Cochrane, Embase, and Scopus. For continuous outcomes, we calculated mean differences (MDs), standardized mean differences (SMDs) and pooled correlation coefficients.
resultsA total of 46 studies met the inclusion criteria, of which 17 contributed to meta-analysis. Children with ASD showed more frequent and severe mealtime behavioral problems than neurotypical peers, with a large difference in BAMBI total scores (SMD = 1.41, 95% CI [0.53, 2.30]). Sensory differences were most pronounced in the tactile domain (SMD = -1.80, 95% CI [-2.52, -1.08]), also evident in taste-smell, visual, and auditory modalities. A moderate correlation was found between sensory processing and feeding difficulties (|r|=0.47, 95% CI [-0.55, -0.44]).
conclusionOur findings demonstrate robust cross-sectional associations between sensory processing differences and feeding difficulties in children with ASD, outlining a clinically relevant behavioral pattern that may guide early developmental assessment and complement existing ASD screening recommendations.
