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 combination of paclitaxel and doxorubicin is among the most successful chemotherapy regimens in cancer treatment. CDK5RAP2, when mutated, causes primary microcephaly. We show here that inhibition of CDK5RAP2 expression causes chromosome mis-segregation, fails to maintain the spindle checkpoint, and is associated with reduced expression of the spindle checkpoint proteins BUBR1 and MAD2 and an increase in chromatin-associated CDC20. CDK5RAP2 resides on the BUBR1 and MAD2 promoters and regulates their transcription. Furthermore, CDK5RAP2-knockdown cells have increased resistance to paclitaxel and doxorubicin, and this resistance is partially rescued upon restoration of CDK5RAP2 expression. Cancer cells cultured in the presence of paclitaxel or doxorubicin exhibit dramatically decreased CDK5RAP2 levels. These results suggest that CDK5RAP2 is required for spindle checkpoint function and is a common target in paclitaxel and doxorubicin resistance.
