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
We obtained A549 and HeLa cell lines that survived and showed stable growth after acute X-ray irradiation at a dose of 15 Gy (hereinafter referred to as A549RR and HeLaRR). Comparative studies of the proliferative activity of original (A549, HeLa) and survived (A549RR, HeLaRR) cells and their sensitivity to additional X-ray irradiation at doses of 2, 4, and 6 Gy by the clonogenic capacity and migration potential (scratch-wound test) were carried out. It was found that the doubling time of the cell population for the A549RR and HeLaRR lines was significantly lower than for the original non-irradiated cells without additional exposure. A549RR and HeLaRR cell lines demonstrated higher resistance to additional X-ray irradiation in terms of clonogenic ability. Migration potential, as one of the critical processes during tumor metastasis, appeared to be significantly higher for A549RR cells up to 24 h after irradiation at a dose of 2 Gy and up to 48 h after irradiation at a dose of 4 Gy. Migration of HeLaRR cells was significantly higher without additional exposure and after irradiation at doses of 2 and 4 Gy, while after irradiation at a dose of 6 Gy, migration activity of HeLaRR cells was significantly suppressed compared to original cells.
