Increase in Oral Streptococcal Endocarditis Among Moderate-Risk Patients: Impact of Guideline Changes on Endocarditis Prevention.
Article in JACC. Advances, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Background: The well-established connection between oral bacteria and infective endocarditis (IE) has prompted discussions about using antibiotic prophylaxis (AP) before invasive dental procedures. In 2007/2008, guidelines restricted AP from moderate and high-risk to exclusively high-risk patients. Objectives: The authors aimed to assess whether the proportion of oral streptococcal IE increased in moderate-risk patients using University Hospital Zurich data from 2000 to 2022. Methods: Adult IE patients were categorized into risk groups based on European Society of Cardiology and Swiss guidelines. The investigation focused on analyzing the proportion of oral streptococcal IE across different risk groups in two distinct periods (1: 2000-2008; 2: 2009-2022). Logistic regression models, adjusted for various factors, were employed. Results: Of 752 IE cases, 163 occurred in period 1, and 589 in period 2. Oral streptococci caused 22% of cases. Proportions of streptococcal IE in period 1 versus period 2 were 24% versus 16% in high-risk, 24% versus 39% in moderate-risk, 33% versus 7% in low-/unknown-risk, and 18% versus 14% in no-risk patients. Compared to the other risk groups, the moderate-risk group had a 22% higher chance of oral streptococcal IE in period 2. After multivariable adjustment, moderate-risk patients had twice the risk of oral streptococcal IE compared to period 1 (OR: 2.59 [95% CI: 1.16-5.81]). Among moderate-risk conditions, congenital valve anomalies were associated with oral streptococcal IE (unadjusted OR: 2.52 [95% CI: 1.71-3.71]). Conclusions: Oral streptococcal IEs increased in the moderate-risk group of patients after the AP guideline change. Exploring the potential necessity for expanding AP indications to certain patient groups with congenital valve anomalies may be warranted.
