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 evaluate the effects of anaesthesia on postoperative outcome in elderly patients who underwent hip fracture surgery.

settingNationwide National Health Insurance Sharing Service database of Korea.

participantsAll patients aged ≥65 years old who underwent hip fracture surgery, covered by the Korean National Health Insurance, between 1 January 2009 and 31 December 2015.

interventionsHip fracture surgery under general anaesthesia (group GA) or regional anaesthesia (group RA), with a principal diagnosis of femoral fracture. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was the anaesthetic-type effect on 30-day mortality and the secondary outcome was postoperative delirium requiring pharmacological intervention.

resultsAmong the 96 289 patients who underwent hip fracture surgery, 25 593 and 70 696 patients received GA and RA, respectively. After propensity score matching, 25 593 remained in each group. Postmatching mortality was lower in the RA than in the GA group (574 (2.24%) vs 654 (2.55%), p=0·0047, 95% CI -0.0099 to 0.0159). Delirium incidence was lower in the RA than in the GA group (5187 (20.27%) vs 5828 (22.77%), p<0·0001, 95% CI 0.019 to 0.045). The incidence of intensive care unit stay and ventilator care was lower in the RA than in the GA group (5838 (22.1%) vs 8055 (31.47%), p<0·0001, 95% CI 0.046 to 0.070 and 459 (1.73%) vs 1207 (4.72%), p<0·0001, 95% CI -0.0024 to 0.023, respectively).

conclusionRA was associated with better outcomes than GA, in terms of mortality, delirium, intensive care unit admission and ventilator care, in elderly patients who underwent hip fracture surgery.
