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

The aim of this study was to determine whether caffeine enhanced radiosensitivity of normal liver tissue in a rat radiation-induced liver disease model. Buffalo rat McA-RH7777 hepatocellular cancer cells and BRL3A normal liver cells were irradiated, and cell cycle distribution and apoptosis rates were analyzed. A rat model of radiation-induced liver disease was established, rats were randomized into four groups: control; caffeine alone; irradiation (IR) alone; and caffeine plus IR (Caff + IR) group. Apoptosis rates in normal rat liver tissue after IR were evaluated by TUNEL staining and caspase-3 Western blot. Transaminase activity was measured and histopathological examination was done after IR. Caffeine abrogated IR-induced G2 phase arrest (Caff + IR vs. IR: 40.9 ± 4.0 vs. 60.7 ± 5.5%, at 12 h after IR) and increased apoptosis rates (Caff + IR vs. IR: 56.1 ± 6.8 vs. 35.5 ± 4.0%, at 72 h after IR) in McA-RH7777 cells, but did not affect IR-induced G2 phase arrest and apoptosis rates at any time point after IR in BRL3A cells. Caffeine did not enhance apoptosis, transaminase activity, or histopathological injury of normal rat liver tissue at any time points after IR. This study suggests that caffeine might not enhance radiosensitivity of normal liver tissue in vivo. In an earlier study, we reported that caffeine enhanced radiosensitivity of human hepatocellular cancer in a nude mice model. Together, these results offer feasibility of clinical application.
