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

purposeThe pulmonary artery (PA) in patients with pulmonary hypertension (PH) becomes dilated. We analyzed the postoperative changes of the main PA after lung transplantation (LuTx).

methodsThe subjects of this retrospective study were 68 LuTx recipients, divided into a PH group (n = 36) and a non-PH group (n = 32), based on preoperative right heart catheterization findings. The PA diameter was measured on chest computed tomography. We evaluated the correlation between the mean pulmonary arterial pressure (mPAP) and the main PA diameter and compared the main PA diameters before and 3 months after LuTx.

resultsThe main PA diameter was significantly correlated with the mPAP (r = 0.423, P < 0.001). Preoperatively, the mean main PA diameter in the PH group was significantly greater than that in the non-PH group. However, by 3 months after LuTx, the main PA diameter in the PH group had decreased significantly from 32.4 ± 6.7 to 26.9 ± 4.8 mm (P < 0.001), while that in the non-PH group had decreased minimally from 28.3 ± 4.9 to 26.4 ± 4.6 mm (P < 0.001), resulting in no significant difference in postoperative main PA diameters between the two groups.

conclusionsThe main PA diameter in recipients with PH was enlarged and correlated with the mPAP. The dilated main PA diameter in PH patients decreased shortly after LuTx.
