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

Chest-Wall-Strapping (CWS), a technique forcing the lung to operate at low volumes, is a model for an oversized lung allograft. Dynamic-dysanapsis describes airway dilation mediated by increased elastic recoil from CWS. We hypothesized that Dynamic-dysanapsis can be quantified via the Dysanapsis-Ratio, defined as the airway-size to lung-volume ratio. Farm-raised pigs (n=3) were mechanically ventilated. Stepwise CT-images throughout the lung deflation limb in control and CWS conditions were analyzed quantifying airway dimensions and lung volume. CWS (30%-reduction in lung-volume) was associated with a significant increase in the Dysanapsis-Ratio (p<0.001). CWS increased airway distensibility at the 6th major branch of the right lower airway (27±7% vs. 39±5%, p=0.04). The dysanapsis-ratio allows quantification of dynamic-dysanapsis with CWS. Dynamic-dysanapsis appears to be a compensatory mechanism to preserve pulmonary gas exchange by airway dilation when the lung is forced to operate at lower lung volumes. Dynamic-dysanapsis furthers the understanding of oversized allografts in lung transplantation.
