Clinical patterns, species-specific correlations, and therapeutic outcomes of nocardiosis in immunocompetent individuals: a systematic analysis based on literature.

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
backgroundNocardiosis, traditionally an opportunistic infection, lacks comprehensive characterization in immunocompetent individuals. This study aimed to describe and analyze the demographics, clinical features, and outcomes of Nocardia infections in this population based on the literature.
methodsA systematic analysis of 530 immunocompetent Nocardia cases (2020-2024) was conducted using reports from PubMed, CNKI, and MedNexus. Demographics, exposures, clinical characteristics, laboratory, treatment, and outcome were recorded and analyzed.
resultsPatients (median age: 59 years; 69.8% male) exhibited pulmonary (46.5%), cutaneous (20.0%), or cerebral (15.7%) involvements. Risk factors included soil/dust exposure (97/530, 18.3%), trauma (44/530, 8.3%), and comorbidities (255/530, 48.1%, e.g., diabetes, bronchiectasis). Cure/improvement (82.6%) group exhibited younger age (P = 0.01) and higher prevalence of local infections (P < 0.001), while more cases of disseminated infection (P < 0.001), N. farcinica (P = 0.01), and unclassified Nocardia spp. (P = 0.02) were in the deterioration/mortality group. Trimethoprim-sulfamethoxazole (71.9%) was the primary therapy. Species-specific patterns demonstrated: N. brasiliensis preferentially linked to cutaneous infections (P < 0.001), N. farcinica to cerebral disease (P < 0.001), and N. cyriacigeorgica to pulmonary involvement (P < 0.001).
conclusionNocardiosis in immunocompetent hosts demonstrates distinct risk profiles, site-specific species associations, and prognostic factors. Early diagnosis, species identification, and antimicrobial therapy are critical for optimizing outcomes. This study underscores the need for heightened clinical suspicion and improved diagnostic protocols in non-immunocompromised populations.
