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

We established a vindesine-resistant (x 11.6) human small-cell lung cancer cell line (H69/VDS) by stepwise exposure of parent line H69 to vindesine. H69/VDS showed cross-resistance to taxol (x 10.1), vincristine (x 6.9) and colchicine (x 3.4) but not to doxorubicin, cisplatin or etoposide. There was no significant difference in intracellular [3H]-vincristine and doxorubicin accumulation between H69 and H69/VDS cells. The human mdr1 mRNA was not detected in either of the cell lines. These results indicated that H69/VDS did not express a typical multidrug resistant phenotype. Addition of 20 microM verapamil enhanced the growth inhibitory effect of vindesine on both H69/VDS (x 12.0) and H69 cells (x 3.8). The amount of total tubulin in H69/VDS cells was lower than that in the H69 parental cells. No significant increase was observed in the amount of total and polymerised tubulins of H69 cells. In H69/VDS cells, however, verapamil increased the amount of total tubulin to the level of parental cells, but decreased the amount of polymerised tubulin. Modulation of tubulin may play a role in the resistance to vindesine.
