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
backgroundAbnormal diffusing capacity for carbon monoxide (DLco) is highly prevalent among people with HIV (PWH) and associated with increased mortality in both PWH and the general population. Because there are no DLco data from East Africa, we characterized the prevalence and risk factors for abnormal DLco in PWH and people without HIV (PWoH) in Uganda.
settingKampala, Uganda.
methodsWe performed a cross-sectional analysis of adults with and without HIV, who were followed longitudinally for lung function change after pneumonia. We used the participants' first American Thoracic Society/European Respiratory Society-compliant DLco measurements post pneumonia. We built multivariable linear and logistic regression models to determine predictors of abnormal DLco. We then developed stratified multivariable models to determine whether the predictors of abnormal DLco differ by HIV serostatus.
resultsAmong 447 individuals, 47.9% were PWH, 17.2% were ever cigarette smokers, 71.4% had tuberculosis (TB) on enrollment, and 9.9% had self-reported past TB. The prevalence of abnormal DLco was 21.7%. In adjusted models, HIV was significantly associated with a lower %predicted DLco, as were past bacterial pneumonia, TB (past and on enrollment), and smoking. After stratification and adjustment, TB (past and on enrollment) was significantly associated with a lower %predicted DLco both among PWH and PWoH; smoking was associated with lower DLco among PWoH, and work fumes exposure was associated with higher odds of DLco < lower limit of normal among PWH only.
conclusionsAbnormal DLco was common post pneumonia in Ugandan adults, and its predictors differed by HIV serostatus. Longitudinal follow-up can help understand the trajectory of and morbidity associated with DLco.
