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

backgroundThe polyethylene insert in a total knee replacement (TKR) can be fixed to the tibial plateau or it can have freedom of rotation and / or translation. It is not yet clear whether there are differences in functional or clinical results between the two prosthesis types.

objectivesThe goal of this review is to assess if a mobile bearing total knee prosthesis provides a better range of motion (ROM) and a better functional outcome than a fixed bearing prosthesis in patients with rheumatoid arthritis or osteoarthritis after total knee arthroplasty. SEARCH STRATEGY: We searched the Cochrane Library (issue 2002-3), Current contents (1996 to September 2002), and MEDLINE (1966 to September 2002). Reference lists of selected articles were also included. SELECTION CRITERIA: Randomised controlled trials or controlled clinical trials were selected which used a functional or clinical outcome measure comparing mobile (rotating and/or sliding) with fixed bearing types. DATA COLLECTION AND ANALYSIS: Data was collected on relevant demographic data and functional outcome measures like Range of Motion, specific measures of activities with daily tasks, and composite knee scores such as Knee Society Score, Hospital for Special Surgery score and similar scores. Only controlled studies comparing a fixed bearing with a mobile bearing type of TKP were considered. MAIN

resultsTwo randomised studies were encountered evaluating the difference in functional or clinical outcome of the two prosthesis types. The methodological quality of the studies was low. The study with the best quality found no difference in ROM, but found a superiority of the mobile bearing on Knee Society Score and Oxford Knee Score and the pain sub scores of these clinical measures. The second study found no differences. REVIEWERS'

conclusionsWe could find no evidence of superiority for one of the two prosthesis types with regard to ROM or functional performance of the patients. The majority (96%) of patients in the 2 included studies had OA. Therefore, the results reflect primarily results in OA patients.
