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

objectiveTo describe primary care physician (PCP) use and continuity of PCP care across the breast cancer care continuum.

designPopulation-based, retrospective cohort study using provincial cancer registries linked to health administrative databases.

settingBritish Columbia, Manitoba, and Ontario.

participantsAll women with incident invasive breast cancer from 2007 to 2012 in Manitoba and Ontario and from 2007 to 2011 in British Columbia.

main outcome measuresThe number and proportions of visits to PCPs were determined. Continuity of care was measured using the Usual Provider of Care index calculated as the proportion of visits to the most-often-visited PCP in the 6 to 30 months before a breast cancer diagnosis (baseline) and from 1 to 3 years following a breast cancer diagnosis (survivorship).

resultsMore than three-quarters of patients visited their PCPs 2 or more times during the breast cancer diagnostic period, and more than 80% of patients had at least 1 PCP visit during breast cancer adjuvant treatment. Contact with the PCP decreased over time during breast cancer survivorship. Of the 3 phases, women appeared to be most likely to not have PCP contact during adjuvant treatment, with 10.7% (Ontario) to 18.7% (British Columbia) of women having no PCP visits during this phase. However, a sizable minority of women had at least monthly visits during the treatment phase, particularly in Manitoba and Ontario, where approximately a quarter of women saw a PCP at least monthly. We observed higher continuity of care with PCPs in survivorship (compared with baseline) in all provinces.

conclusionPrimary care physicians were generally involved throughout the breast cancer care continuum, but the level of involvement varied across care phases and by province. Future interventions will aim to further integrate primary and oncology care.
