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
backgroundNeonatal hypoglycaemia is a common metabolic disorder affecting up to 15% of healthy neonates and a higher proportion of at-risk infants. Oral 40% dextrose gel has emerged as a promising, low-cost intervention, but recent evidence remains inconsistent. This updated meta-analysis evaluated the efficacy of 40% oral dextrose gel for preventing and treating neonatal hypoglycaemia.
methodsWe systematically searched PubMed, Embase, Web of Science, Scopus and the Cochrane Library from inception to March 2026 for randomized controlled trials evaluating 40% oral dextrose gel in neonates at risk for or with confirmed hypoglycaemia. The primary outcome was hypoglycaemia. We used R software (version 4.5.0) for the analysis.
resultsEight RCTs comprising 4368 neonates were included. Dextrose gel did not significantly reduce hypoglycaemia, treatment success, recurrent hypoglycaemia, neonatal intensive care unit (NICU) admission, breastfeeding at discharge or formula feeding. Sensitivity analysis excluding Harding et al. (2021) for NICU admission yielded a statistically significant 24% reduction. Trim-and-fill adjustment for recurrent hypoglycaemia and formula feeding did not alter conclusions.
conclusionsCurrent evidence did not demonstrate a statistically significant reduction in overall hypoglycaemia, treatment failure, recurrent hypoglycaemia, NICU admission or breastfeeding interruption after administration of oral 40% dextrose compared with control. While safe and low-cost, current evidence does not support routine use as a standalone intervention. Heterogeneity across protocols and populations warrants standardization in future trials.
