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

rationaleMounting data suggest that immune cell abnormalities participate in the pathogenesis of pulmonary arterial hypertension (PAH).

objectiveTo determine whether the T lymphocyte subset composition in the systemic circulation and peripheral lung is altered in PAH.

methodsFlow cytometric analyses were performed to determine the phenotypic profile of peripheral blood lymphocytes in idiopathic PAH (IPAH) patients (n=18) and healthy controls (n=17). Immunocytochemical analyses of lymphocytes and T cell subsets were used to examine lung tissue from PAH patients (n=11) and controls (n=11). MEASUREMENTS AND MAIN

resultsIPAH patients have abnormal CD8+ T lymphocyte subsets, with a significant increase in CD45RA+ CCR7- peripheral cytotoxic effector-memory cells (p=0.02) and reduction of CD45RA+ CCR7+ naive CD8+ cells versus controls (p=0.001). Further, IPAH patients have a higher proportion of circulating regulatory T cells (T(reg)) and 4-fold increases in the number of CD3+ and CD8+ cells in the peripheral lung compared with controls (p<0.01).

conclusionsAlterations in circulating T cell subsets, particularly CD8+ T lymphocytes and CD4+ T(reg), in patients with PAH suggest that a dysfunctional immune system contributes to disease pathogenesis. A preponderance of CD3+ and CD8+ T lymphocytes in the peripheral lung of PAH patients supports this concept.
