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

purposeThe purpose of this study is to evaluate the risk of sequential bilateral total knee arthroplasty (TKA) under 1 anesthesia in patients 75 years or older. MATERIALS AND

methodsPatients aged 75 years or older who underwent sequential bilateral TKA (bilateral group, n=159) and unilateral TKA (unilateral group, n=159) between 2002 and 2012 were selected. All patients were evaluated for underlying medical diseases, such as cardiac, pulmonary, and renal problems, and high-risk patients were recommended to postpone the surgery. We compared the underlying diseases, major postoperative complications, and the length of hospital stay between bilateral and unilateral groups.

resultsThe prevalence of underlying diseases of the bilateral group was 74.8% and major complications occurred in 6 patients (3.8%). The prevalence of underlying diseases of the unilateral group was 52.4% and complications were observed in 4 patients (2.4%). Although the complication rate of the bilateral group was slightly higher than that of the unilateral group, the difference was not statistically meaningful (p=0.204). The length of hospital stay was 21.9 days for the bilateral group and 24.9 days for the unilateral group.

conclusionsThere was no significant difference in postoperative complications between groups. The result shows that bilateral TKA can be relatively safe compared with unilateral TKA in patients 75 years or older. However, careful selection of low-risk patients is advised.
