Predictive analysis of influencing factors on HIV testing behavior among college students in Shanxi, China.
Article in BMC public health, 2025. 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
backgroundDespite high level of acceptance, human immunodeficiency virus (HIV) testing rate among Chinese college students remained low. Few studies examined the extent of the relationship between HIV testing behavior and its influencing factors among college students. This study aimed to investigate HIV testing rates among college students and examine key factors associated with HIV testing behavior.
methodsThe convenience sampling method was used for college students from four colleges in Shanxi from October to December 2023. A network questionnaire survey was designed to collect information on general demographics, sexual encounters, and HIV testing behavior. Logistic regression and the decision tree model were combined to identify key factors influencing HIV testing behavior among college students.
resultsAmong 3,115 college students, the rate of HIV testing was 2.5% (n = 77) in the past year. The binary logistic regression analysis indicated that students who had received school sex education (aOR = 2.78, 95%CI:1.51-5.09), homosexual orientation (aOR = 3.12, 95%CI:1.09-8.93), and had engaged in a sexual encounter in the past year (aOR = 5.13, 95%CI:2.50-10.53) were positively associated with HIV testing behavior. In addition, compared with freshmen, only sophomores were more likely to undergo HIV testing (aOR = 1.87, 95%CI:1.01-3.43). Further, the decision tree model revealed that the most significant factor influencing HIV testing behavior was having had a sexual encounter in the past year, followed by being in love and having received school sex education. The accuracy rate of the decision tree model was 97.53%, the precision rate was 97.53%, and the F1 value was 0.99.
conclusionHIV testing rate among the college students was relatively low. Sexual experience, being in love and school sex education were significant predictors of HIV testing behavior. Being offered HIV self-testing services and implemented sex education programs at an early age may promote HIV testing behavior among college students.
