Vascular insufficiency in the extremities following jellyfish-sting envenomation in Malaysia.

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
Introduction: Vascular insufficiency is an uncommon but potentially limb-threatening complication of jellyfish envenomation, with limited documentation in Southeast Asia. This study characterizes its epidemiology, clinical course, and response to targeted vasodilator therapy in Malaysia. Methods: A retrospective cohort review was conducted for confirmed jellyfish-sting cases complicated by vascular insufficiency reported to the Remote Envenomation Consultancy Services (RECS) from 2017 to 2022. Demographic, geographic, clinical, and management data were extracted from RECS consultation logs. Serial Doppler ultrasound findings and treatment responses were analysed descriptively. Results: Among 105 jellyfish sting consultations, four (3.8 %) cases of vascular insufficiency were identified, all occurring in coastal Penang and affecting children aged 7-12 years. All primary stings involved the upper limbs; two had concurrent lower limb lesions. The onset of peripheral numbness and cyanosis occurred on day three post-sting. Doppler ultrasonography revealed subcutaneous oedema, reduced arterial calibre, and diminished flow velocities consistent with arterial vasospasm. All patients received intravenous iloprost (0.5-2 ng/kg/min) with gradual tapering, guided by clinical and Doppler parameters. Rapid improvement in perfusion was documented in all cases, with minimal adverse effects (vomiting, dyspnoea, haematuria). Hospitalization lasted 12-32 days. Three patients achieved full functional recovery; one had residual scarring and contracture. No deaths occurred. Conclusion: Delayed-onset arterial vasospasm can complicate paediatric jellyfish stings, particularly in the upper limb. Early recognition of evolving ischemic signs and timely initiation of iloprost with structured tapering may avert tissue loss. Broader drug availability and standardized treatment algorithms are needed to optimize outcomes in resource-limited coastal settings.
