Seek and you shall find! Prevalence and trends of chlamydial and gonococcal infections in a high-density urban area in Italy around the COVID era: a laboratory-based survey.
Article in Sexually transmitted infections, 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
backgroundA comprehensive understanding of the epidemiology of
methodsWe collected data on all samples submitted to the Microbiology of IRCCS Azienda Ospedaliero-Universitaria of Bologna for CT/NG testing. Data were stratified by year, sex, age, testing site and anatomical sampling site.
resultsA total of 63 569 samples from 46 501 individuals were analysed. CT prevalence was 7.2%, with a peak in those aged 18-25 and a male-to-female ratio of 1.56. Although one-third of tests were from family counselling centres or gynaecologists, the highest CT positivity was found at the STI outpatient clinic (69%) and infectious diseases centres (13%). NG prevalence was 4.8%, with very low rates in family and gynaecology settings. NG showed a striking male predominance (M:F=8.6). For both CT and NG, we observed (1) a rise in case numbers over time, especially in males; (2) a decline during the COVID-19 pandemic followed by a rebound; and (3) a notable proportion of pharyngeal and rectal infections.
conclusionsThis study highlights key epidemiological trends of CT and NG infections based on population characteristics, healthcare access points and the influence of external factors such as COVID-19 pandemic. These findings underscore the importance of targeted screening and prevention programmes and reinforce the role of laboratory-based surveillance to guide public health interventions.
