Androgen Receptor and PI3K Pathway Activity in Ovarian Cancer.
Article in Journal of cancer research and therapeutic oncology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 sought to evaluate androgen receptor (AR) and PI3K pathway activity in ovarian cancer cell lines and tissue and determine if either pathway was correlated with growth of ovarian cancers. AR expression and activity were quantified using immunohistochemistry (IHC) and RT-qPCR in six ovarian cancer cell lines and 51 tissue samples. Phospho-mTOR and AKT expression were quantified by IHC as well. Cell growth was assessed in the presence of AR modulating drugs and metformin. We found that despite robust AR expression and activity, no cell line was dependent on androgen for growth. However, metformin inhibited activity in five of the six cell lines. Patient tissues had large variation in AR expression and activity, as well as in expression of phospho-mTOR and AKT, but none of these variables correlated with progression-free survival (PFS). AR expression and activity did not predict the dependence of ovarian cancer cell lines on androgens for growth, and AR expression and activity did not correlate with PFS. This result suggests that AR expression as a criterion for patient selection for clinical trials evaluating molecules targeting AR may not predict response for ovarian cancer patients.
