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
backgroundChlamydia trachomatis (CT) infection is one of the most prevalent genital tract infections which has been reported to have adverse effects on reproductive health. However, doctors will only test for CT infection if there are associated symptoms. This study aimed to compare outcomes before and after implementing a CT screening protocol to evaluate whether to encourage more routinized CT screening.
methodsA hospital-based survey was conducted at Shaoxing Maternity and Child Health Care Hospital. The study was divided into two time periods, T1 (July 2021-June 2022, before screening protocol) and T2 (July 2022-June 2023, after screening protocol). The study included females aged over 16 years who agreed to CT testing at four clinics, including obstetrics, infertility, termination of pregnancy and gynecology. The nucleic acid amplification results were utilized to ascertain the presence of chlamydia infection in cervical secretions.
resultsAfter active promotion of CT screening, 15,005 females were tested, with an average age of 32.2 years (SD = 8.3), which were more than double the previous number and significantly younger (P < 0.05). Significant differences in the number of people CT screened were observed in the obstetrics (2.5%-66.5%, P < 0.05) and termination of pregnancy (7.5%-45.3%, P < 0.05) clinics. The positive rates of CT in T1 and T2 were 6.8% (491/7230) and 5.2% (774/15005), respectively. The implementing chlamydia screening identified an additional 184 (11-195) infected pregnant women in obstetrics clinics (a similar number of outpatient visits). The age group with the highest proportion was 26-30 years (27.6%), followed by 21-25 years (21.4%) and 31-35 years (21.1%).
conclusionsActive screening significantly improves the detection of chlamydia in women's health clinics. Pregnant individuals and those seeking pregnancy termination were previously overlooked in CT screening efforts but required increased attention.
