Blastomycosis, Histoplasmosis, and Coccidioidomycosis in Outpatient Community-Acquired Pneumonia.
Article in JAMA network open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Importance: Laboratory testing is necessary to distinguish blastomycosis, coccidioidomycosis, or histoplasmosis from other causes of community-acquired pneumonia (CAP). Robust data about testing for and diagnosis of these fungal diseases among patients with CAP throughout the US are lacking. Objective: To examine proportions and characteristics of (1) adult outpatients with CAP who underwent diagnostic testing for blastomycosis, coccidioidomycosis, or histoplasmosis; and (2) tested patients who received diagnoses of these diseases. Design, Setting, and Participants: This retrospective cohort study used 2017 to 2023 commercial health insurance claims data from the Merative MarketScan Commercial/Medicare Database. Adult outpatients with diagnosis codes for unspecified CAP were included. Main Outcomes and Measures: The primary outcome was the proportion of patients who underwent fungal diagnostic testing. The secondary outcomes were the proportions of tested patients who received diagnoses of blastomycosis, coccidioidomycosis, or histoplasmosis. Multivariable logistic regression models were used to estimate adjusted odds ratios (aORs) for characteristics independently associated with receiving a diagnosis of coccidioidomycosis or histoplasmosis. Results: Among 573 994 patients (318 152 female [55%]; median [IQR] age, 54 [41-63] years) with unspecified CAP, 25 822 (5%) underwent fungal diagnostic testing, which occurred a median (IQR) of 3 (1-6) health care visits after the initial CAP diagnosis. Among tested patients, 755 (3%) received a blastomycosis, coccidioidomycosis, or histoplasmosis diagnosis code. Rash (aOR, 3.24; 95% CI, 2.27-4.63), lymphadenopathy (aOR, 1.74; 95% CI, 1.15-2.63), myalgia (aOR, 1.66; 95% CI, 1.11-2.49), chest pain (aOR, 1.65; 95% CI, 1.35-2.02), and receipt of antibiotics from multiple classes (aOR, 1.40; 95% CI, 1.17-1.67) were independently associated with increased odds of receiving a coccidioidomycosis diagnosis. Autoimmune inflammatory disease (aOR, 3.00; 95% CI, 1.72-5.21), chest pain (aOR, 1.84; 95% CI, 1.20-2.82), and abnormal weight loss (aOR, 5.15; 95% CI, 2.71-9.79) were associated with increased odds of receiving a histoplasmosis diagnosis. Conclusions and Relevance: In this cohort study of patients with unspecified CAP, testing rates for blastomycosis, coccidioidomycosis, and histoplasmosis were low in many locations. Increased awareness of these fungal infections may help increase timely testing for fungal diseases among patients with CAP, decrease health care utilization and inappropriate antibiotic use, and improve patient outcomes.
