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

backgroundThere is an information gap in literature regarding postoperative outcome of total knee arthroplasty (TKA) in patients with hardware in-situ from the previous knee surgery. The present study aims to evaluate impact of retained hardware on short-term outcome of TKA patients.

methodsPerioperative radiographs of patients who had undergone TKA between 2007 and 2012 were reviewed and patients in whom partial or complete retention of hardware was evident after TKA were included. These patients were matched in 1 to 2 ratio based on age (+/- 2 years), gender, surgeon and year of surgery to a group of patients that underwent primary TKA without hardware in the affected knee. The average follow up of these patients was 43.45 (range 12-155.2) months. Complication rates were compared between the two groups using statistical tests that took into account the matched data structure.

resultsWe included a total of 55 cases and 110 controls. The incidence of complications was higher, although not all statistically significant, in the case group. Only mechanical complications were significantly different in the cases group (5.5% versus 0%,

conclusionPresence of retained hardware around the knee may predispose the patient to a higher rate of complications particularly mechanical complications of the implant after TKA. Further studies are required to investigate impact of retained hardware around the knee in patients undergoing TKA.
