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 examine differences in referral patterns in a nationally representative sample between primary care physicians (PCP) practicing in rural vs nonrural areas and changes over time. STUDY

designUsing the 2005-2016 National Ambulatory Medical Care Survey and multivariate logit regression models, I compare referral patterns of PCPs in rural vs nonrural areas. DATA COLLECTION: Multiple years of data were combined. PRINCIPAL

findingsA PCP visit was 1.9 percentage points (95% confidence interval: 0.1 pp, 3.8 pp) more likely to result in a referral in nonrural areas than rural areas, controlling for physician and patient characteristics, a 17 percent increase. This difference is driven by a widening gap in referral rates between nonrural and rural areas over time, with large differences in later periods. The regression-adjusted predicted probability of a PCP visit resulting in a referral was 71 percent higher in nonrural than rural areas in 2013-2014 and 92 percent higher in 2015-2016.

conclusionsRecognizing that the optimal PCP referral rate is unknown, referrals are less common in rural areas with a widening gap in recent years. This difference may reflect specialist availability, distance to care, or patient preferences. As changes occur to health care financing and delivery, continuing to monitor practice patterns is important to ensure patients are receiving appropriate levels of care across geographic regions.
