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

backgroundIn women with early stage, hormone receptor (HR)-positive (HR(+)) breast cancer, the 21-gene recurrence score (RS) assay quantifies recurrence risk and predicts chemotherapy responsiveness. Recent data suggest that not all women with early-stage, HR(+) disease receive this testing. We examined sociodemographic, clinical, and attitudinal factors associated with RS testing receipt and the RS testing effect on chemotherapy use in black and white patients. PATIENTS AND

methodsWomen with newly diagnosed invasive, nonmetastatic breast cancer were recruited and interviewed to collect sociocultural and health care process data; clinical data were collected from charts. Of the sample (n = 359), 270 had HR(+) disease. Primary analysis focused on those with HR(+) node-negative disease (n = 143); secondary analyses included node-positive women. Logistic regression models evaluated factors associated with receipt of RS testing and chemotherapy.

resultsAmong women eligible for the 21-gene assay, 62 patients [43%] received RS testing. In multivariable analysis, older age (odds ratio, 1.04 per 1 year increase; 95% confidence interval, 1.01-1.08) was associated with RS testing after adjustment for covariates. Chemotherapy use was 23%. In multivariable analysis, positive attitudes about chemotherapy and greater risk of recurrence were associated with chemotherapy use (P < .05).

conclusionPatterns of genomic testing might vary according to age. Efforts to understand factors associated with low testing rates will be important.
