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

Background: It is of great clinical significance to further explore new strategies and potential combined therapeutic targets for gastric cancer. This study aimed to investigate the synthetic lethal effect of RBBP8 molecular intervention combined with a poly ADP ribose polymerase (PARP) inhibitor in non-BRCA mutant gastric cancer and clarify the mechanism by which RBBP8 regulates homologous recombination repair. Methods: The role of RBBP8 in DNA damage repair was observed using bioinformatic analysis, western blot analysis, and immunofluorescence. The synthetic lethal effect was verified using 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt (MTS)and flow cytometry apoptosis experiments. Results: Among the patients with gastric cancer treated with chemotherapy, the prognosis of patients with high RBBP8 expression levels was worse (homologous recombination [HR] = 1.54, Conclusion: RBBP8 is involved in homologous recombination repair, and molecular intervention into RBBP8 could achieve a synthetic lethal effect with PARP inhibitor treatment in gastric cancer cells.
