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

Rice bran oil (RBO) is a rich source of lipophilic bioactive compounds that may contribute to antioxidant, anti-inflammatory, and bone-health-promoting activities. This study investigated the effects of RBOs containing tocopherols, tocotrienols, and γ-oryzanol derived from Thai pigmented and non-pigmented rice cultivars on oxidative stress, inflammatory responses, and bone-remodeling-related activities. The content of tocopherols, tocotrienols, and γ-oryzanol was determined by high-performance liquid chromatography (HPLC). Reactive oxygen species (ROS) production was determined in human fetal osteoblast (hFOB 1.19) cells where nitric oxide (NO) and inducible nitric oxide synthase (iNOS) production were evaluated in RAW264.7 cells. Following compositional profiling and correlation analyses of antioxidant and anti-inflammatory activities, three representative RBOs were subsequently evaluated for their effects on bone-remodeling-related activities in hFOB 1.19 cells through alkaline phosphatase (ALP) activity and the production of osteocalcin (OC), osteoprotegerin (OPG), and receptor activator of nuclear factor kappa-B ligand (RANKL). Additionally, calcification was investigated by Alizarin Red S staining. Pigmented RBOs, particularly Khao' Hom Nil and RD69, contained higher levels of tocopherols, tocotrienols, and γ-oryzanol than non-pigmented RBOs. These oils significantly suppressed ROS, NO, and iNOS production, which correlated with tocopherol, tocotrienol, and γ-oryzanol content, while enhancing ALP activity, OC and OPG production, reducing RANKL levels and the RANKL/OPG ratio, and promoting matrix mineralization. Overall, pigmented RBOs represent promising natural sources of lipophilic bioactive compounds with potential antioxidant, anti-inflammatory, and bone-remodeling-related activities under in vitro conditions.
