1 · What the graph read from it

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.

2 · The registry

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

backgroundVenous gas embolus secondary to deep soft tissue infection is a rare but potentially fatal condition in emergency settings that requires urgent medical intervention. CASE PRESENTATION: We report a case of a 32-year-old female with an invasive mole undergoing chemotherapy who presented with fever and severe bilateral lower limb pain. Point-of-care ultrasound (POCUS) revealed gas emboli on B-mode and Doppler-mode imaging within the femoral veins and further detected emphysematous changes in adjacent intramuscular and subcutaneous tissues, suggesting critical infection and initiating immediate clinical reassessment. The patient was subsequently confirmed to have severe hypoxemia and sepsis, with computed tomography demonstrating extensive gas-forming lesions, ultimately leading to cardiac arrest despite advanced life support.

conclusionThis case highlights the critical role of POCUS in the rapid detection of intravascular gas and deep soft tissue infection in time-critical conditions.
