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 hip arthroplasty (THA) relieves pain and restores function in patients with severe rheumatoid arthritis and osteoarthritis. Over the past few decades, several authors have attempted to assess the efficacy and safety of simultaneous bilateral THA compared with staged bilateral THA. The purpose of this meta-analysis is to compare the mortalities and complications between simultaneous bilateral THA and staged bilateral THA.

methodsA literature search to identify eligible studies was undertaken to identify all relevant articles published until August 2018. We included studies that compared simultaneous bilateral THA and staged bilateral THA and their effects on mortality and complications. The outcomes included mortality, the occurrence of deep venous thrombosis (DVT), the occurrence of pulmonary embolism (PE), respiratory complications, cardiovascular complications, digestive system complications and the occurrence of dislocation. Stata 12.0 was used for the meta-analysis.

resultsNineteen studies involving 59,257 patients were identified; among them, 16,758 patients were selected for treatment with simultaneous bilateral THA, and 42,499 patients were chosen for the purpose of staged bilateral THA. The meta-analysis results demonstrated that there was no significant difference between simultaneous bilateral THA and staged bilateral THA in terms of mortality (risk ratio [RR] = 1.15, 95% CI = 0.76, 1.74; P = .520). Compared with staged bilateral THA, simultaneous bilateral THA was associated with a reduction in the occurrence of DVT, PE and respiratory complications (P < .05). There were no significant differences in the cardiovascular complications, digestive system complications or the occurrence of dislocation and infection (P = .057).

conclusionsWe observed that the prevalence of DVT, PE and respiratory complications was considerably lower with the use of simultaneous bilateral THA than with the use of staged bilateral THA. Thus, simultaneous bilateral THA is a considerably safer procedure than staged bilateral THA in selected THA patients.
