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

purposeSimultaneous bilateral unicompartmentsl knee arthroplasty (BUKA) is considered safe and effective. We performed a systematic review to assess the postoperative outcomes.

methodsThe US National Library of Medicine (PubMed/MEDLINE), Google Scholar, and the Cochrane Database of Systematic Reviews were queried for publications.

resultsTen articles were included with 765 simultaneous BUKA. Overall complication rate was 7.0%, survivorship was 97.6% at mean 17 months follow-up. No differences were reported between simultaneous and staged BUKA.

conclusionSimultaneous BUKA is as safe as staged BUKA, it is associated with decreased length of stay and operative time, although it has an increased rate of blood transfusion.
