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

backgroundWe examined trends in the treatment of femoral neck fractures over the last two decades.

methodsWe used Medicare Part A administrative data to identify patients hospitalized for closed femoral neck fracture from 1991 to 2008. We used codes from the International Classification of Diseases, Ninth Revision, to categorize treatment as nonoperative, internal fixation, hemiarthroplasty, and total hip arthroplasty. We examined differences in treatment according to hospital hip fracture volume, hospital location (rural or urban), and teaching status.

resultsOur sample consisted of 1,119,423 patients with intracapsular hip fractures occurring from 1991 to 2008. We found a generally stable trend over time in the percentage of patients managed with nonoperative treatment, internal fixation, hemiarthroplasty, and total hip arthroplasty. We found little difference in surgical treatment across different groups of hospitals (high volume compared with low volume, urban compared with rural, and teaching compared with nonteaching). The percentage of acute care hospitals treating hip fractures remained fairly constant (74.8% in 1991 to 1993 and 69.0% in 2006 to 2008). The median number of hip fractures treated per hospital did not change (thirty-three in 1991 to 1993 and thirty-three in 2006 to 2008). There was no increase in the percentage of fractures treated in high-volume hospitals over time (57.7% in 1991 to 1993 and 57.1% in 2006 to 2008) and little reduction in the percentage of fractures treated in low-volume hospitals (5.8% in 1991 to 1993 and 5.5% in 2006 to 2008).

conclusionsThere has been little change in the trends of operative and nonoperative treatment for proximal femoral fractures over the last two decades, and there was little evidence of regionalization of hip fracture treatment to higher-volume hospitals.
