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.
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
Purpose: The present study was conducted to examine the profile of oxidized phospholipids (OxPLs) in uveitis using rat model and clinical specimens, and to elucidate the role of macrophages in the metabolism of OxPLs. Methods: Lewis rats were immunized with a bovine interphotoreceptor retinoid- binding protein (bIRBP) peptide with complete Freund's adjuvant (CFA) to induce experimental autoimmune uveitis (EAU). The aqueous humor (AH) was collected 2 weeks after immunization. Fifty-four human AH specimens, among which 21 eyes had a history of chronic uveitis, were collected during their cataract surgery. The profile of OxPLs in the AH specimens were analyzed by liquid-chromatography tandem mass spectrometry (LC-MS/MS). In addition, the involvement of macrophages in the viability of cells treated by OxPLs was investigated through a WST-1 assay using ARPE-19 cells and C57BL/6 mouse alveolar macrophages (AMs). The influence of macrophages in the trend of OxPLs was traced by thin layer chromatography (TLC) using AMs. Results: Six species of OxPLs were detected in the AHs of rats and humans. The content of each OxPL was higher in the uveitis group. Four kinds of OxPLs found in AHs showed cytotoxicity to ARPE-19 cells in a dose-dependent manner. The cytotoxicity was reduced by pretreatment of OxPLs with AMs. When the OxPLs were applied on AMs, a marked reduction of OxPLs in the medium was observed. Conclusions: The OxPLs formed by intraocular inflammation could induce cytotoxicity. The present findings suggest that the phagocytic macrophages emerging in the inflammation site eliminate OxPLs, and prevent intraocular tissue damage following uveitis.
