Effect of oral pre-emptive analgesia on pain management after total knee arthroplasty: a protocol for systematic review and meta-analysis.
Article in BMJ open, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
introductionTotal knee arthroplasty (TKA) is currently regarded as an effective treatment for knee osteoarthritis, relieving patients' pain and significantly enhancing their quality of life and activity levels, allowing them to return to work and daily life after surgery. However, some TKA patients suffer from varying degrees of postoperative residual pain and opioid abuse, which negatively impacts their recovery and quality of life. It has been reported that preoperative treatment with multimodal analgesics improves postoperative pain and reduces opioid consumption. However, there is no conclusive evidence that pre-emptive analgesia provides the same benefits in TKA. In order to inform future research, this protocol focuses on the efficacy and safety of oral analgesics used in TKA pre-emptive analgesia. METHODS AND ANALYSIS: We will search the literature on the involvement of pre-emptive analgesia in the management of pain in TKA from the PubMed, EMBASE, MEDLINE, the Cochrane Central Register of Controlled Trials and the Cochrane Database of Systematic Reviews, from their inception to 1 February 2023. Additionally, clinical registry platforms will be investigated to collect data for ongoing studies. Using the Cochrane Risk of Bias Tool, the quality assessment will be conducted. RevMan V.5.4 will be used for the meta-analysis. The statistic ETHICS AND DISSEMINATION: No ethical approval and consent is required for this systematic review. Moreover, the results of this systematic review will be disseminated through peer-reviewed publications and conference presentations. PROSPERO REGISTRATION NUMBER: CRD42022380782.
