Leukocytosis and tobacco use during pregnancy.
Article in International journal of gynaecology and obstetrics: the official organ of the International Federation of Gynaecology and Obstetrics, 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
objectiveFactors such as tobacco and other toxic substance use, obesity, associated comorbidity, and intercurrent infections can cause a proinflammatory state and modify analytical parameters. The objective of this study is to identify smoking-induced leukocytosis in pregnant women across all three trimesters of pregnancy to aid in their clinical assessment.
methodsDemographic and analytical data were reviewed for 300 pregnant women included in the WOMAP trial during the three trimesters of pregnancy, evaluating white blood cell counts, neutrophil and lymphocyte percentages, and hemoglobin and hematocrit values. Leukocytosis association with smoking was assessed via logistic regression.
resultsThe sample had a mean age of 31.60 ± 6.00 years, with a mean body mass index of 24.70 ± 5.35 kg/m
conclusionTobacco use during pregnancy was associated with elevated white blood cell counts and leukocytosis in all trimesters. In pregnant women with leukocytosis, smoking history should be reviewed, and smoking cessation should be encouraged.
