Preoperative education for reducing patient anxiety in elective hip and knee arthroplasty - a systematic review and meta-analysis.
Review in Perioperative medicine (London, England), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPreoperative educational interventions are often implicitly regarded as a useful and cost-effective means of improving arthroplasty care. However, previous research in this area is limited - both in terms of age and clinical heterogeneity. This review adds to the existing literature by investigating the relationship between educational interventions and clinically relevant outcome measures, whilst also incorporating a larger sample size, and more stringently defined eligibility criteria. The primary outcome was preoperative anxiety. Secondary outcomes were patient knowledge score, postoperative pain, time-to-discharge, quality-of-life, and surgical complication rate.
methodsA systematic review and meta-analysis of 19 randomised controlled trials. Inclusion criteria specified an adult population receiving elective hip or knee arthroplasty, an intervention group participating in a structured educational intervention, and a control group receiving no education beyond routine preoperative consenting. Outcome data were independently extracted by the review team, before being pooled for statistical analysis using comparison of mean differences and a random effects model.
resultsResults showed small, but statistically significant, improvements for the outcomes of patient anxiety (SMD -0.37, 95% CI -0.63 to -0.11), knowledge (SMD +0.37, 95% CI +0.05 to +0.69), and pain (SMD -0.31, 95% CI -0.47 to -0.15). However, the results for other outcome measures were not statistically significant.
conclusionsFindings show a trend in favour of education for reducing anxiety and postoperative pain, though effect sizes were small, and the amount of practical benefit remains questionable due to inter-trial clinical heterogeneity. It was also observed that multi-format interventions may be beneficial for patients with greater anxiety, learning needs, or pain. Further research is necessary due to a lack of trials with reproducibly described interventions.
