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
The potential of EHT 6706, a novel tubulin-binding agent, was investigated in combination with ionizing radiation (IR) and with conventional cytotoxic chemotherapy agents. Cell proliferation, cell cycle, apoptosis and clonogenic assays were performed in five human cancer cell lines: H460 (non small cell lung carcinoma, NSCLC), HCT116 and HCT116 p53-/- (colorectal cancer), MDA-MB-231 (breast cancer), and MiaPaca2 cells (pancreatic cancer). The drug inhibited cell proliferation in all cell lines. This effect was associated with G2/M arrest and activation of apoptosis in a dose-dependent manner. The drug was then tested in combination with chemotherapy and IR in vitro. Effects on proliferation and clonogenic survival were analyzed. EHT 6706 treatment inhibited clonogenic survival synergistically with IR in H460 and MiaPaca2 cell lines. In the remaining cell lines, the effects of EHT 6706 and IR were additive. For H460 and MiaPaca2 cell lines, the highest effect was seen when cells were exposed for 20 h to EHT 6706 before being irradiated. EHT 6706 also exerted additive inhibition of proliferation when given in combination with conventional chemotherapy agents, such as oxaliplatin, cisplatin and gemcitabine in H460 and MiaPaca2 tumor cell lines. These data show that EHT 6706 could act synergistically with IR and additively with chemotherapy in tumor cell lines in vitro. This provides a good rationale to further assess EHT 6706 in combination protocols and confirm these effects in vivo.
