Randomized trial protocol of interscalene nerve block vs liposomal bupivacaine injection after total shoulder arthroplasty.
Article in Medicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It carries an expression of concern. Not yet cited in PubMed.
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
backgroundThe possibility of local infiltration analgesia (LIA) replacing interscalene blockade (ISB) as an integral component of a multimodal clinical pathway for total shoulder arthroplasty (TSA) needs to be further investigated. We thus further designed a randomized controlled study to compare LIA with ISB in the treatment of TSA.
methodsThis blinded and randomised study was performed after approval of the institutional review board in the first affiliated hospital of Jinan University. The included patients were all aged over 18 years and underwent shoulder arthroplasty because of osteoarthritis of the shoulder. Subjects were randomized into 2 groups as follows: LIA or ISB. The primary outcome of this noninferiority study is opioid consumption within the first 24 hours following surgery. Secondary outcomes included pain scores, length of hospital stay, complication, and satisfaction score. P value < .05 was considered statistically significant.
resultsFor the present trial, we hypothesized that there would be no difference in pain score levels and opioid medication use throughout admission.
trial registrationThis study protocol was registered in Research Registry (researchregistry5640).
