Bird fanciers' lung induced by exposure to duck and goose feathers.

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
patientFemale, 60 FINAL DIAGNOSIS: Bird fanciers' lung Symptoms: Cough productive • hypoxia • short of breath • substernal chest pain MEDICATION: - Clinical Procedure: - Specialty: -
objectiveRare disease.
backgroundHypersensitivity pneumonitis (HP) is a group of inflammatory interstitial lung diseases caused by hypersensitivity reactions from repeated insults of inhalation of fine particulate organic dusts derived from environmental sources. Bird fanciers' lung (BFL) is the most common form of HP, with an estimated prevalence of 0.5-7.5% and is observed in individuals who develop a hypersensitivity response to avian droppings or antigens on bird feathers. CASE REPORT: A 60-year-old woman presented to our care with shortness of breath with exertion. She was hypoxic with oxygen saturation of 70% on room air. The CTA of the chest revealed a diffuse bilateral ground glass density in the lung parenchyma with a mosaic attenuation pattern. On further questioning she explained that she collected many duck and goose feathers she found on the ranch and placed them in a vase at home. Transbronchial lung biopsy revealed non-caseating granulomas, aggregates of epithelioid macrophages, and patchy mononuclear cell infiltration with lymphocytes and fibrotic tissue. The patient clinically improved and was discharged home on the 6(th) hospital day with prednisone 20 mg daily, with clinical improvement noted on subsequent follow up visits.
conclusionsThere is no specific clinical manifestation; abnormal laboratory test results help establish a definitive diagnosis. The best diagnostic tool is the correlation of symptom onset with the environmental exposure. The prognosis is excellent after a single episode of HP, but continuous re-exposure carries the risk of progressive pulmonary impairment.
