Lactate as a biomarker for discriminating and assessing prognosis of neonatal necrotising enterocolitis: A systematic review and meta-analysis.
Review in Pakistan journal of medical sciences, 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
Background and Objective: Neonatal necrotising enterocolitis (NEC) is a severe neonatal gastrointestinal disease associated with high morbidity and mortality. The present systematic review and meta-analysis examined if blood lactate could be used in the discrimination and prognosis of NEC. Methodology: PubMed, Embase, Scopus, and Web of Science databases were searched for relevant studies from the database inception to 26 January 2026. Diagnostic studies comparing lactate levels between NEC and control groups were pooled using standardised mean differences (SMDs). Prognostic studies evaluating mortality were pooled using odds ratios (ORs) under a random-effects model. Results: Nine studies were included, comprising four diagnostic and five prognostic studies. Lactate levels were significantly higher in neonates with NEC compared with controls (SMD = 1.66, 95% CI 0.78-2.55 I Conclusions: This review suggests that lactate levels are significantly higher in neonates with NEC as compared with controls. However, while elevated lactate tends to be associated with increased mortality risk, substantial heterogeneity and limited evidence preclude its use as a standalone prognostic marker. Further research is needed to strengthen the present conclusions.
