Transcriptome Analysis of the Effects of X-Ray Radiotherapy on Non-small-cell Lung Cancer Using Next-generation Sequencing.

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
BACKGROUND/
aimThis study investigated the acute effects of flattening filter (FF) and flattening filter-free (FFF) beams on gene expression in non-small-cell lung cancer (NSCLC). MATERIALS AND
methodsThirty-six adult athymic nude mice were divided into five groups. The control group did not undergo any radiotherapy or treatment procedures, whereas in the lung cancer (LCa) group, a cancer model was created but not irradiated. LCa models received 20 Gy radiotherapy with FF at 400 MU/min, or with FFF at 1,000 or 1,800 MU/min dose rates. The mice were irradiated 20 days after A549 cancer cell-line implantation and sacrificed 48 h after irradiation for genetic analysis.
resultsTwelve genes were identified as being common across all radiotherapy groups. The expression of most of these genes changed as the dose rate increased. Seven of these genes were also common to the LCa and control groups. Three genes down-regulated in the untreated cancer group showed increased expression with higher dose rates in treated groups. Significant differences were observed in glutamatergic synapse, actin cytoskeleton regulation, and steroid synthesis in FF-400 and FFF-1000. The FFF-1800 group exhibited significant changes in RNA transport, actin cytoskeleton regulation, and phagosome-associated pathways.
conclusionFFF beams induced more extensive and pronounced gene-expression changes compared to FF beams in NSCLC.
