Gender differences and psychosocial stress in upper respiratory tract infections: insights from healthy and hematological cancer cohorts.
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
backgroundUpper respiratory tract infections (URTIs) are shaped by sex and gender, with stress potentially playing a critical role. However, the interplay remains poorly understood. This study examined whether women experience higher stress than men, contributing to increased URTI susceptibility and symptom burden.
methodsOur monocentric, prospective study included 273 healthy individuals (cohort H) and 194 stem-cell recipients (cohort P), enrolled between 11/2013 and 05/2017. Participants were aged ≥ 18 years. Data included demographics, household composition, smoking behavior, cancer-related characteristics, URTI-symptoms, and perceived stress (measured via 4-item perceived stress scale, PSS-4). Participants were categorized by biological sex, assuming alignment with gender.
resultsIn cohort H (50% women, mostly ≤ 30 years), women reported more moderate/severe URTI-symptoms than men (57% vs. 36%, p < 0.001, φ = 0.210) and higher PSS-4 scores [t(271) = 2.84, p < 0.001, d = 0.636]. In women, stress modestly correlated with symptom burden (r = 0.15, p = 0.04). Sex and age were significant predictors of stress. In cohort P (40.5% women, mostly ≥ 30 years), men reported more URTI symptoms (83% vs. 68%, p = 0.021), while PSS-4 did not differ by sex. Stress correlated with symptom burden (r = 0.293, p < 0.001), particularly in women (r = 0.385, p < 0.001). Symptom burden was the only independent predictor of stress.
conclusionThe relationship between sex, stress, and URTI burden varies by health status. Healthy women, especially younger adults, experience higher stress and more severe symptoms, though stress only modestly relates to symptom burden. In immunocompromised patients, stress strongly reflects symptom severity, particularly in women, with minimal sex differences in stress. These findings highlight a complex interplay between sex, psychosocial stress, and infection outcomes, emphasizing the need for interventions addressing both biological and psychosocial determinants, particularly in vulnerable populations.
