Clinical characteristics and obstetric outcomes of dengue fever in pregnancy: a nationwide population-based study in Taiwan.
Article in BMC pregnancy and childbirth, 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
backgroundDengue fever is a major mosquito-borne viral infection with rising global prevalence in tropical and subtropical regions. Pregnant women represent a particularly vulnerable population due to altered immune and physiological responses. While dengue is endemic in Southeast Asia, population-based data on maternal outcomes in East Asian populations with advanced healthcare systems like Taiwan are scarce.
methodsA nationwide retrospective descriptive, non-comparative study identified 264 pregnant women with dengue (2012-2018) via the Taiwan NHIRD. Outcomes were analyzed descriptively; comparisons with national statistics are illustrative rather than formal risk estimates.
resultsThe median maternal age was 32 years. The most common maternal intervention was Cesarean delivery (68.6%), while ICU admission occurred in 9.1%. For neonatal outcomes, a composite of preterm delivery or incubator care (aggregated due to coding limitations) occurred in 34.9%. Notably, the rate of low birth weight (9.5%) remained comparable to national baselines despite high intervention rates.
conclusionsHigh rates of obstetric intervention despite preserved biological outcomes may reflect defensive clinical practices and diagnostic uncertainty during epidemics. Refined guidelines are needed to balance safety and avoid unnecessary surgery.
