Prevalence, risk factors, and medical costs of Chlamydia trachomatis infections in Shandong Province, China: a population-based, cross-sectional study.

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
backgroundA population-based study of Chlamydia trachomatis (CT) infections is essential in designing a specific control program; however, no large investigation of CT infections among the general population in mainland China has been conducted since 2000. We aimed to determine the prevalence, risk factors, and associated medical costs of CT among residents, 18-49 years of age, in Shandong, China.
methodsFrom May to August 2016, a multistage probability sampling survey involving 8074 individuals was distributed. Data were collected via face-to-face interviews, followed by self-administered questionnaire surveys. First-void urines were collected and tested for CT and Neisseria gonorrhoeae (NG) using nucleic acid amplification.
resultsThe weighted prevalence of CT infection was 2.3% (95% confidence interval [CI], 1.5-3.2) in females and 2.7% (1.6-3.8) in males. Women, 30-34 years of age, had the highest prevalence of CT infections (3.5%, 2.6-4.4), while the highest prevalence of CT infections in males was in those 18-24 years of age (4.3%, 0.0-8.8). Neisseria gonorrhoeae infection had a prevalence of 0.1% (0.0-0.3) in women and 0.03% (0.0-0.1) in men. Risk factors for CT infections among females included being unmarried, divorced, or widowed (odds ratio [OR], 95% CI 3.57, 1.54-8.24) and having two or more lifetime sex partners (3.72, 1.14-12.16). Among males, first intercourse before 20 years of age (1.83, 1.10-3.02) and having two or more lifetime sex partners (1.85, 1.14-3.02) were associated with CT infections. The estimated lifetime cost of CT infections in patients 18-49 years of age in Shandong was 273 million (range, 172-374 million) China Renminbi in 2016.
conclusionsThis study demonstrated a high burden of CT infections among females < 35 years of age and males < 25 years of age in Shandong. Thus, a CT infection control program should focus on this population, as well as others with identified risk factors.
