1 · What the graph read from it

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.

2 · The registry

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

Areas with reduced density are a common finding with thin-slice computed tomography (CT) examinations of lung parenchyma. Diffuse and localized patterns can be differentiated. The most frequent cause for a diffuse decrease in density is pulmonary emphysema which can be classified into centrilobular, panlobular and paraseptal emphysema based on the distinct anatomical features. A mosaic pattern (due to mosaic perfusion or air trapping) is also characterized by a diffuse decrease in density. Focal cystic changes can be differentiated from emphysematous changes and mosaic patterns which do not reveal wall structures. Langerhans cell histiocytosis and lymphangioleiomyomatosis are the most frequent cystic diseases of the lung parenchyma. Based on the geometry and anatomical distribution of the cysts a differentiation is mostly possible. Rare diseases leading to a reduced lung density include the Birt-Hogg-Dubé syndrome, lymphoid interstitial pneumonia as well as congenital diseases or diseases which are acquired during early childhood, such as cystic adenomatoid malformation or Swyer-James syndrome.
