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

Cryptococcosis is a systemic mycosis affecting immunocompromised individuals (mainly IMPORTANCE: Cryptococcosis is a fungal infection with mortality exceeding 75%, predominantly affecting immunocompromised individuals-including transplant recipients and people living with HIV-but also capable of infecting healthy people. Treatments are lengthy, toxic, and increasingly ineffective due to antifungal resistance. Two major contributors to therapeutic failure are biofilms-protective fungal communities encased in a self-produced matrix-and persister cells, a dormant subpopulation that survives lethal drug concentrations and reactivates infection once treatment stops. This study reveals that efflux pumps-proteins that expel drugs from fungal cells-are not only resistance mechanisms but also active contributors to biofilm construction. Critically, persister cells reactivate their efflux pumps upon recovery, providing a biological explanation for infection recurrence. Two drug combinations-fluconazole + FK506 and fluconazole + octyl protocatechuate-synergistically disrupted biofilms and reduced persister cell viability while potentially lowering drug doses and toxicity, pointing toward safer, more effective strategies for cryptococcosis.
