Interventions for metabolic bone disease of prematurity: A systematic review and meta-analysis.
Article in Metabolism open, 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
Introduction: Metabolic bone disease of prematurity (MBDP) affects up to 30 % of very low birth weight infants; however, evidence regarding prevention and treatment strategies remains limited. We aimed to evaluate the efficacy and safety of nutritional, mechanical, and pharmacological interventions for MBDP. Methods: Following PRISMA 2020 guidelines, we searched five databases from inception to May 5, 2025, for studies evaluating interventions for MBDP in preterm infants (<37 weeks or <1500g). Primary outcomes included MBDP incidence, bone mineral density, and safety profiles. Random-effects meta-analyses, trial sequential analysis (TSA), and GRADE assessments were conducted. Results: Eighteen studies (1577 infants) from ten countries met inclusion criteria. Nutritional prophylaxis significantly reduced MBDP incidence by 54 % (risk ratio [RR] = 0.46, 95 % confidence interval [CI] 0.30-0.68, P-value<0.001), with early calcium/phosphorus supplementation achieving 74-84 % risk reduction. TSA confirmed conclusive evidence, with cumulative Z-score (-5.99) crossing the O'Brien-Fleming boundary at 270.9 % of required information size. Number needed to treat was five at 40 % baseline risk. Mechanical interventions improved bone mineral content by 28 % (P-value<0.01), quantitative ultrasound speed-of-sound (mean difference [MD] = 75.3 m/s, 95 % CI 45.2-105.4), and weight gain (MD = 5.11 g/kg/day, 95 % CI 3.95-6.27). Both interventions demonstrated favorable safety profiles, with mechanical protocols reporting no adverse events. Conclusions: Nutritional prophylaxis conclusively reduces MBDP incidence, while mechanical interventions effectively improve bone mineralization. Although no studies directly evaluated combined approaches, the complementary mechanisms of nutritional and mechanical interventions suggest that optimal prevention may involve integrating both strategies. Critical gaps persist in orthopedic management, necessitating future research on fracture protocols and surgical interventions.
