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

What is already known about this topic?: Partner tracing (PT) represents an established public health strategy for identifying undiagnosed individuals with human immunodeficiency virus (HIV) infection and contributes to controlling sustained HIV transmission. What is added by this report?: Partner tracing among newly diagnosed HIV-infected men who have sex with men (MSM) demonstrates effectiveness in identifying undiagnosed infected individuals, with regular sexual partners showing higher likelihood of HIV-positive detection. However, phylogenetic analysis revealed that only a small proportion of epidemiologically linked pairs exhibited genetic linkage. What are the implications for public health practice?: Sustained implementation and broader application of partner tracing may serve a critical role in HIV epidemic control by facilitating early identification of undiagnosed infections and interrupting potential transmission chains. Integrating partner tracing with phylogenetic analysis enhances the capacity to distinguish actual transmission chains from coincidental behavioral associations, thereby improving transmission linkage identification accuracy and informing more targeted intervention strategies.
