Edema in Pregnancy: A Common yet Understudied Maternal Concern.
Article in Cureus, 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
objectiveThis study aims to assess the prevalence of lower-extremity edema among postpartum patients and identify potential associated risk factors.
methodsA survey evaluating the presence of lower-extremity edema and potential risk factors was conducted among 52 patients across two hospitals in La Crosse, Wisconsin, and Mankato, Minnesota, for six months between August 1, 2022, and January 31, 2023. All participants were informed of their rights and provided written consent. All adult postpartum women were screened for inclusion. Exclusion criteria included communication barriers, active cancer, deep vein thrombosis, infection involving the pelvis or lower extremities, recent lower-extremity fractures, recent non-obstetric surgery, or current participation in experimental treatments. Data were collected using a paper-based survey. Logistic regression analysis was performed using BlueSky statistical software (BlueSky Statistics LLC, Chicago, IL, USA) to examine the relationship between edema and potential risk factors, including delivery type, pregnancy complications, and comorbid conditions such as obesity and chronic diabetes. Models were constructed with the dependent variable (presence of edema) regressed on selected independent variables (risk factors).
resultsOf the 52 postpartum participants, 18 (34.6%) reported experiencing edema of pregnancy (EOP). Among them, 13 (76.5%) reported edema during both pregnancy and the postpartum period, 4 (23.5%) reported edema only during pregnancy, and 1 (5.9%) reported postpartum-only edema. Obesity emerged as a statistically significant risk factor for the development of EOP (p < 0.05).
conclusionThis study identified obesity as a statistically significant risk factor for EOP. Although several other factors did not reach statistical significance, their potential clinical relevance warrants further investigation. Future large-scale, longitudinal studies are needed to better understand the multifactorial influences of maternal characteristics and comorbidities on the development of pregnancy-related edema.
