Pulmonary nodular opacities in children with hereditary hemorrhagic telangiectasia.
Article in Pediatric radiology, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundHereditary hemorrhagic telangiectasia (HHT) is a rare inherited disorder of vascular endothelium that can result in the formation of pulmonary arteriovenous malformations (pAVMs). We observed that small pulmonary nodules, possibly representing early vascular malformations, are more common in these children than in the general population.
objectiveTo describe and characterize the small pulmonary nodules seen on chest CT examination in the lungs of children with HHT. MATERIALS AND
methodsWe followed 19 children who had undergone chest CT as part of their initial diagnostic evaluation in the HHT clinic of a pediatric hospital. Chest CT scans were reviewed independently by two radiologists blinded to clinical data. Pulmonary nodules were analyzed according to lobar distribution, anatomic position in the lung (outer, mid, inner third), shape (round, linear, V- or Y-shaped, ill-defined), presence of overt AVMs, and nodule size (<or= or >5 mm). We also reviewed a control group of chest CT scans performed on 25 age-matched children.
resultsA total of 35 pulmonary nodules were identified on the CT scans in 15 of the 19 children. Multiple nodules were seen in eight children (42%), solitary nodules were seen in seven children (37%) and no nodules were seen in the remaining four children (21%). The nodules were found to be nonspecific with regard to multiple factors other than their anatomic position within the lung. The chest CT scans of 2 of the 25 age-matched controls revealed a total of only four nodules, a significantly lower total (P = 0.0001 vs. children with HHT).
conclusionNonspecific nodules are commonly seen in children with HHT.
