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

objectiveEvaluate income disparities in receipt of needle biopsy among Medicare beneficiaries and describe the magnitude of this variation across physician peer groups.

methodsThe Surveillance, Epidemiology and End Results (SEER)-Medicare database was queried from 2007-2009. Physician peer groups were constructed. The magnitude of income disparities and the patient-level and physician peer group-level effects were assessed.

resultsAmong 9770 patients, 65.4% received needle biopsy. Patients with low income (median area-level household income < $33K) were less likely to receive needle biopsy (58.5%) compared to patients with high income (≥ $50K) (68.6%; adjusted odds ratio 0.77; 95% confidence interval (CI) 0.65-0.91). Needle biopsy varied substantially across physician peer groups (interquartile range 43.4-81.9%). The magnitude of the disparity ranged from an odds ratio (OR) of 0.50 (95% CI 0.23-1.07) for low vs. high income patients to 1.27 (95% CI 0.60-2.68). The effect of being treated by a physician peer group that treated mostly low-income patients on receipt of needle biopsy was nearly three times the effect of being a low-income patient.

conclusionsNeedle biopsy continues to be underused and disparities by income exist. The magnitude of this disparity varies substantially across physician peer groups, suggesting that further work is needed to improve quality and reduce inequities.
