Exploring psychological symptom associations among people living with HIV using an apriori algorithm.
Article in BMC infectious diseases, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAlthough antiretroviral therapy has extended the lifespan of people living with HIV (PLWH), psychological symptoms are still prevalent. Given the complexity of psychological symptoms, effective interventions need to consider the interactions and associations of symptoms.
aimTo explore psychological symptom association rule mining through Apriori algorithm analysis among PLWH in China.
methodsThis study was based on cross-sectional, multi-center, large sample data. From April 2022 to April 2023, we recruited 3040 participants with confirmed HIV-1 infections from six HIV sentinel hospitals in Beijing, Shanghai, Shenzhen, Nanning, Kunming, Baoshan and Jiaxing of China through convenience sampling to assess their psychological symptoms. The Apriori algorithm was employed to analyze the association rules among psychological symptoms in PLWH.
results26 of the 40 psychological symptoms entered into the association rules. We selected the top 126 association rules based on confidence. By visualizing the arrow directions of these association rules, three gradients were identified. Of the 40 symptoms, “ forgetting things that occurred recently ” and “ nervousness ” was the first gradient. LIMITATIONS: The cross-sectional design can only describe the co-occurrence of psychological symptoms, lacking causal insights and needing longitudinal data.
conclusionsOur findings highlight the interconnected nature of psychological symptoms among PLWH and underscore the need for prioritized, network-based interventions. CLINICAL TRIAL: Clinical trial number: not applicable.
