Radiological resolution of community-acquired pneumonia in hospitalised patients in North India.

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
backgroundCommunity-acquired pneumonia (CAP) is the most common infectious cause of death, and radiology is a corner stone of its management. No data are available from India regarding the radiological resolution of CAP in the current antibiotic era. We set out to study determine the radiological resolution of CAP.
methodsThe study was conducted in a 1250-bedded North Indian hospital. Consecutive consenting adults admitted with CAP over a period of 2 years from July 2019 were enrolled for the study. The patients were subjected to routine investigations and radiological imaging and treated with standard antibiotic/antiviral therapy as per standard protocols and followed daily till clinical resolution and discharge from the hospital. Serial chest radiographs were taken at 2, 4, 8, and 12 weeks after admission, and the follow-up terminated at either complete clinical or radiological resolution.
results176 patients (age 20 to 90 years, median 60 years; 109 (61.9%) male) participated. Eighty-nine (50.6%) patients were current smokers. Chest radiographs revealed lobar consolidation as the most common finding (n = 97, 55.1%), followed by pulmonary infiltrates (n = 73, 41.5%) and pleural effusion (n = 6, 3.1%); 44 (25%) patients had multi-lobar consolidation The rates of radiological resolution at 2, 4, 8, and 12 weeks follow-up were 30%, 38.5% (cumulative 68.5%), 25.7% (cumulative 94.2%), and 5.9% (cumulative 100%) of patients, respectively. The average time taken for radiological resolution was 31.49 (±20.2) days in 70 cases, where documented. On multi-variate analysis, smoking was an independent factor for delayed radiological resolution (P = 0.007).
conclusionRadiological resolution of CAP occurs in the majority (68.5%) of the patients at 4 weeks from the time of clinical presentation, with smoking as an independent risk factor for delayed (>4 week) radiological resolution. Clinicians can wait for 4 weeks to document radiological recovery unless clinical features suggest otherwise.
