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 mortality and postoperative morbidity associated with simultaneous bilateral or staged bilateral total knee arthroplasty (TKA).

methodsWe identified eligible studies in PubMed (1980-2010), OVID MEDLINE (1980-2010) and the Cochrane library. Data were extracted and evaluated by two reviewers independently. Data analyses were conducted with Stata 10.0.

resultsFourteen studies met our inclusion criteria. Combined results showed that the prevalence of mortality [OR = 3.202, 95% CI (1.852-5.537)], mortality at 30 days postoperatively [OR = 5.564, 95% CI (2.392-12.939)] and neurological complications [OR = 2.906, 95% CI (1.200-7.037)] were significantly higher in the population who had undergone simultaneous TKA compared with those who had undergone staged TKA. The prevalence of infection, pulmonary embolism, deep-vein thrombosis, and cardiac complications between the two populations was not significantly different.

conclusionCompared with staged bilateral TKA, simultaneous bilateral TKA might carry a higher potential risk of postoperative complications. Patients should be aware of this information when deciding whether to proceed with simultaneous bilateral TKA. The poor quality of the studies calls into question the robustness of the analyses.
