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

backgroundTotal knee arthroplasty (TKA) is one of the most successful orthopedic surgeries performed in recent decades. However, controversies still exist between conducting simultaneous or staged bilateral TKA. The objective of this study is to conduct a systematic review assessing the clinical outcome associated with simultaneous bilateral and staged bilateral total knee arthroplasty (BTKA).

methodsA search was applied to CNKI, Embase, Medline, and Cochrane central database (January 2000-July 2018). All studies that compared simultaneous bilateral TKA (simBTKA) with staged bilateral TKA (staBTKA) without language restriction were reviewed, and qualities of included studies were assessed using the Newcastle-Ottawa Scale. Data were pooled and a meta-analysis completed.

resultsThe 18 studies were identified to be eligible. The 18 comparative studies published from 2001 to 2018, covered 73617 participants in the simBTKA group and 61838 in the staBTKA group, respectively. Results of meta-analyses indicated that simBTKA showed a lower risk of deep infection and respiratory complications, but increased mortality, pulmonary embolism (PE), and deep-vein thrombosis (DVT) compared with staBTKA. There were no significant differences in revision, superficial infection, arthrofibrosis, cardiac complications, neurological complications and urinary complications between procedures.

conclusionsSince there are risks and benefits to both procedures, these potential complications must be interpreted in light of each individual patient's needs and concerns. Further research must be conducted, in the form of a randomized clinical trial, to evaluate the outcomes mentioned in this review.
