Impact of COVID-19 School Learning Model on STI Testing, Diagnosis Rates, and Related Behaviors.
Article in Sexually transmitted diseases, 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
backgroundThe COVID-19 pandemic and associated changes in school learning model reshaped students' lives and may have impacted sexual behaviors and healthcare access.
methodsWe used a difference-in-differences (DID) approach to compare changes in sexual behaviors, human immunodeficiency virus (HIV)/sexually transmitted infection (STI) testing, and STI diagnosis rates from 2019-2021 between jurisdictions where high school was primarily virtual versus in-person for the 2020-2021 school year. We used behavioral data from local jurisdictions administering Youth Risk Behavior Survey and reported chlamydia and gonorrhea diagnosis rates for 15- to 19-year-olds in corresponding counties from AtlasPlus. Learning model was defined using the COVID-19 School Data Hub, school/governmental policies, news, or other documentation. We used survey-weighted logistic regression for behavioral outcomes and Poisson regression for diagnosis rates. The DID estimates were parameterized as the interaction between year and learning model.
resultsTwenty-four local jurisdictions (16 virtual, 8 in-person) were included. Compared to in-person learning, virtual learning was significantly associated with a relative increase in condom use from 2019 to 2021 (DID odds ratio [DID-OR], 1.42; 95% confidence interval [95% CI], 1.12-1.79) and relative decreases in STI testing (DID-OR, 0.75; 95% CI, 0.59-0.96), chlamydia diagnoses (DID incidence rate ratio [DID-IRR], 0.86; 95% CI, 0.84-0.88), and gonorrhea diagnoses (DID-IRR, 0.83; 95% CI, 0.79-0.87). Learning model was not significantly associated with changes in sexual intercourse ever or in past 3 months, multiple sex partners in past 3 months, alcohol/drug use before last sex, or ever HIV testing.
conclusionsEfforts are needed to maintain access to sexual health services during and after public health emergencies involving schools and increase STI testing access for students, especially those who attended school virtually.
