Intensive vital signs monitoring reduces 30-day mortality among stroke patients: A cohort study from Tanzania.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundStroke is a leading cause of mortality and disability worldwide, with disproportionate impacts in low- and middle-income countries due to limited healthcare resources. Monitoring vital signs during the acute phase of a stroke is critical for detecting complications. We aimed to assess the impact of intensive (6-hourly) versus usual practice (12-hourly) vital sign monitoring strategies on stroke outcomes at Mloganzila Hospital, Tanzania.
methodsWe conducted a prospective cohort study of patients with first-ever stroke admitted to Mloganzila Hospital between October 2023 and March 2024. Participants were assigned to 6-hourly or 12-hourly vital signs monitoring for the first 72 hours, after which all received usual care. Monitoring frequency reflected routine clinical practice; no investigational treatments were introduced, and therapeutic decisions were unaffected by group allocation. The primary outcome was 30-day all-cause mortality; secondary outcomes included functional disability measured by the modified Rankin Scale. Ethical approval was obtained, and informed consent was secured. Data were analyzed using SPSS version 26 and Stata version 15. Survival was assessed using Kaplan-Meier analysis, and factors associated with 30-day mortality identified using modified Poisson regression.
resultsOf 306 participants (mean age: 59.6 ± 14.0 years; 53.6% male), 63.7% experienced a hemorrhagic stroke. There were no significant differences in stroke severity or functional disability at 72 hours between the groups. Intensive vital signs monitoring was associated with significantly lower 30-day mortality compared to usual monitoring (35.9% vs. 49.7%; p = 0.015).
conclusionFrequent monitoring of vital signs during the acute phase of stroke may enhance clinical stability and improve patient outcomes. Our findings demonstrate a significant reduction in 30-day mortality with intensive monitoring. These findings support the establishment of dedicated stroke units with structured monitoring protocols in resource-limited settings to strengthen stroke care systems and reduce preventable deaths.
