The "Tree-in-Bud" Pattern on Chest CT: Radiologic and Microbiologic Correlation.
Article in Lung, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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
backgroundTree-in-bud (TIB) is a radiologic pattern seen on high-resolution chest CT reflecting bronchiolar mucoid impaction occasionally with additional involvement of adjacent alveoli. Its microbiologic significance has not been systematically evaluated.
objectivesWe aimed to establish the incidence of the TIB pattern as a proportion of all patients undergoing chest CT and to identify its etiology wherever possible.
methodsWe included all patients with TIB pattern detected on chest CT in our institution from January 2007 to June 2012 and correlated this radiologic finding to the microbiologic etiology, which were available, for each patient.
resultsDuring the study period, TIB pattern was described in 326 patients, which is 1.8% of all chest CTs. Of these, 220 (67.5%) patients had an infectious etiology and 34 (10.4%) had aspiration pneumonia. Other presumptive etiologies were in 13 (4%) lung malignancy, 31 (9.5%) other malignancies, 20 cases (6%) inconclusive etiology or incidental findings, and 8 (2.5%) had other inflammatory disorders. The relative incidence of the various organisms isolated reflected the overall incidence of these bacteria in community- or hospital-acquired populations independent of the TIB pattern. No correlation was found between distribution of TIB, the immune status, and the organism isolated.
conclusionsTIB pattern reflects endobronchiolar inflammation due mainly but not exclusively to an infectious cause. The microbiologic etiology in patients with this finding is similar to that of the general population (community acquired versus hospital acquired).
