Prevalence and trends of gestational diabetes in a large university hospital in Lebanon before and during the COVID-19 pandemic.
Article in BMC public health, 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
backgroundThe prevalence of gestational diabetes mellitus (GDM) is increasing worldwide in parallel with obesity, maternal age, improved screening methods and wider screening coverage. The objective of our study was to determine the prevalence of GDM in Lebanon and to evaluate its risk factors before and during the COVID-19 pandemic.
methodsRecords of 2595 pregnant women who gave birth at the Hôtel-Dieu de France Hospital in Beirut, were collected retrospectively from 2018 to 2022. GDM was determined by documentation in the maternity fileward. A univariate analysis was performed to assess the factors affecting GDM. The χ² test, Fisher's exact test, independent samples T-test, and ANOVA were used for this purpose.
resultsThe mean age was 32.03 years (± 4.75). The mean BMI at the beginning of pregnancy was 24.86 kg/m² (± 8.99), and the mean gestational weight gain (GWG) was 12.17 kg (± 5.06). The overall prevalence of GDM was 4.1%, increasing significantly from 2.9% to 6.4% between 2018 and 2022 (p value = 0.007). The peak in 2020 was temporally associated with the onset of the COVID-19 pandemic and the compounding socioeconomic crises. The risk factors associated with GDM included older age (p = 0.003) and obesity (p = 0.004).
conclusionThe increasing trend of GDM incidence emphasizes the importance of implementing evidence-based prevention, diagnostic, and treatment strategies.
