Clinical characteristics of ocular toxocariasis in adults in north China.

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
aimTo investigate the clinical features of adult patients with ocular toxocariasis (OT) in north China and to diagnose adults OT patients in early stage.
methodsClinical data of 24 adults with OT were retrospectively analyzed. Slit lamp photographs and fundus photographs and other imaging examinations of all the patients were reviewed. A questionnaire concerning the pet ownership and place of residence was completed to investigate the possible infection origin. Descriptive statistical analyses were performed on the demographic data, clinical features, funduscopic findings and ELISA results.
resultsAmong the 24 patients diagnosed with OT by Toxocara IgG antibody in intraocular fluid, 16 (66.7%) eyes were right eye. The onset age of 12 eyes (50.0%) was between 30 and 40 years old, and 21 (87.5%) eyes were of peripheral granuloma type. The most common sign was vitreous opacity. Granulomas were detected in all the eyes, and 20 (83.3%) patients resided in rural area. In 4 patients, the concentration of anti-Toxocara antibody both in anterior humor and in vitreous humor were detected, and the results showed the concentration in vitreous humor was much higher than aqueous humor.
conclusionOur study analyzes the clinical manifestation of OT in adults, which may have been under-recognized before. Eye side, residence, and detection of granuloma may help us in diagnosis of OT in patients with monocular vitreous opacity. For adult patients with presumed OT, negative results of anti-Toxocara antibody in anterior humor cannot rule out the possibility of OT, further detection of vitreous humor is suggested for final diagnosis.
