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 hypoxic nature of cells within solid tumors limits the efficacy of anticancer therapies such as ionizing radiation and conventional radiomimetics because their mechanisms require oxygen to induce lethal DNA breaks. For example, the conventional radiomimetic enediyne neocarzinostatin is 4-fold less cytotoxic to cells maintained in low oxygen (hypoxic) compared with normoxic conditions. By contrast, the enediyne C-1027 was nearly 3-fold more cytotoxic to hypoxic than to normoxic cells. Like other radiomimetics, C-1027 induced DNA breaks to a lesser extent in cell-free, or cellular hypoxic, compared with normoxic environments. However, the unique DNA interstrand cross-linking ability of C-1027 was markedly enhanced under the same hypoxic conditions that reduced its DNA break induction. Although the unique chemistry of C-1027 allows it to concurrently generate both DNA breaks and cross-links in normoxic cells, a low oxygen environment represses the former and promotes the latter. Thus, treatment with C-1027 offers a facile approach for overcoming the radioresistance associated with poorly oxygenated cells.
