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

This study evaluated the mortality rate, major complications, and early outcomes of single anesthetic bilateral total hip and knee arthroplasty compared with unilateral and staged procedures. A total of 37,828 total hip and knee arthroplasties were evaluated with 6-month Oxford 12 scores. Major complications and mortality rates were recorded. Analysis of variance tables were used for statistical analysis. The single anesthetic bilateral group were significantly younger (P < .001), with their age-adjusted postoperative Oxford 12 scores significantly better (P < .001) than the other 2 groups. The surgeons involved, in general, performed more than 25 total knee and hip arthroplasties per year. There was 1 death within the first 6 months occurring in the staged bilateral group and was unrelated to the surgery. The complication rate as reported by patients was low in all groups, and there was no significant difference. The results show that, in selected patients, single anesthetic bilateral total knee or hip arthroplasty is a safe, low-risk procedure with very good patient-generated outcome scores at 6 months when performed by an experienced surgeon.
