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

purposeAlthough computed tomography (CT) has been used previously to assess disease severity in lymphangioleiomyomatosis (LAM), the associations between the extent of pulmonary cysts on CT and six-minute walk test (6MWT), matrix metalloproteinases (MMPs) and vascular endothelial growth factor (VEGF-D) are not well established. We performed a cross-sectional study to quantify the extent of pulmonary cysts in CT and to establish their correlations with pulmonary function tests (PFTs), 6MWT results, including a composite index (desaturation-distance ratio, DDR), and levels of VEGF-D and MMPs in LAM.

methodsTwenty-three LAM patients underwent CT scanning to automatically quantify the extent of pulmonary cysts and performed PFTs and 6MWT. Serum levels of MMP-2, MMP-9, and VEGF-D were also measured.

resultsThe severity of pulmonary cystic involvement was mild (the extent of cysts was 6.8 %) and correlated best with FEV1/FVC (r = -0.84), residual volume (r = 0.66), DLCO (r = -0.82), the DDR index (r = 0.77), and desaturation during the 6MWT (r = -0.81). There was a weak correlation with VEGF-D (r = 0.45), but no association was found with MMP-2 and MMP-9.

conclusionsThe severity of pulmonary cystic involvement was mild in this sample of LAM patients and correlated best with airway obstruction, air trapping, reduced DLCO, the DDR index, and desaturation during the 6MWT. Serum VEGF-D cannot be completely defined as a valuable marker of disease severity and there may be a mechanism independent of MMPs to explain the formation of pulmonary cysts.
