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

Intrapleural talc is used to produce pleurodesis in malignant pleural effusions. Prior in vivo studies have documented an acute inflammatory response to talc in the pleural space but the cellular source of cytokines has not been identified. The aim of this study was to investigate the acute response of rabbit pleural mesothelial cells challenged with talc used for pleurodesis and compare it to prior studies of the response to talc in the rabbit pleural space. Cultured rabbit pleural mesothelial cells (PMC) were exposed to talc (25 mug/cm(2)) for 6, 24, or 48 h and assessed for viability, necrosis, and apoptosis by flow cytometry, Trypan Blue exclusion, and immunocytochemistry, and for the production of interleukin-8 (IL-8), vascular endothelial growth factor (VEGF), and transforming growth factor-beta(1) (TGF-beta(1)) by ELISA. More than 50% of the PMC remained viable 48 h after talc stimulation. The PMC that were nonviable were identified as either apoptotic or necrotic, with roughly 20% in each category over the 48 h. At 6 h, the IL-8, VEGF, and TGF-beta(1) levels produced by talc-exposed PMC increased significantly and remained elevated for up to 48 h. These cytokine levels rose at similar times and at the same or higher levels than have been measured in the rabbit pleural space in prior studies. We report that viable, talc-exposed, pleural mesothelial cells may actively mediate the primary inflammatory pleural response in talc-induced pleurodesis.
