Trial reportPloS one2017
Randomized blinded trial of standardized written patient information before total knee arthroplasty.
Trial report in PloS one, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01747759 (Evaluation of a Preoperative Education in Total Knee Arthroplasty), which is not on this map. Cited by 8 papers, 2 of them syntheses that pooled 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.
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.

Abstract
backgroundThe effect of patient education before total knee arthroplasty (TKA) is controversial. No consensus exists about the optimal content of educational interventions. In a previous study, we developed and validated an educational booklet on the peri-TKA management of knee osteoarthritis. PURPOSES: Our primary purpose was to evaluate the impact of the educational booklet on knowledge among patients awaiting TKA. PATIENTS AND
methodsThis randomized controlled single-blind trial evaluated standard information by the surgeon with or without delivery of the educational booklet 4-6 weeks before primary noncomplex TKA in patients aged 55-75 years with incapacitating knee osteoarthritis. Patients were enrolled at a French surgical center between June 2011 and January 2012. A patient knowledge score was determined at baseline, on the day before TKA, and 3-6 weeks after TKA, using a self-administered questionnaire developed for our previous study. The assessor was blinded to group assignment.
resultsOf 44 eligible patients, 42 were randomized, 22 to the intervention and 20 to the control group, all of whom were included in the analysis. The groups were comparable at baseline. The intervention was associated with significantly better patient knowledge scores.
conclusionsAn educational booklet improves knowledge among patients awaiting TKA. A study assessing the impact of the booklet combined with a exercise program would be helpful. LEVEL OF EVIDENCE: Level I, randomized controlled double-blind trial; see S1 CONSORT Checklist.
