Comparison of two different volumes of 0.5%, ropivacaine used in ultrasound-guided adductor canal block after knee arthroplasty: A randomized, blinded, controlled noninferiority trial.
Article in Journal of anaesthesiology, clinical pharmacology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Background and Aims: The aim of this study was to establish noninferiority of 10 mL of 0.5% ropivacaine as compared to 20 mL of 0.5% ropivacaine; for choosing right dose in adductor canal block (ACB) after knee arthroplasty (KA), this trial was conducted. Material and Methods: Forty patients undergoing bilateral KA with postoperative ultrasound-aided ACB were randomized: Group A patients received 20 mL 0.5% ropivacaine in the right limb and 10 mL 0.5% ropivacaine in the left limb. Group B patients received 10 mL of 0.5% ropivacaine in the right limb and 20 mL of 0.5% ropivacaine in the left limb. Catheter is positioned for intermittent boluses every 12-h up to 48 h. Results: In the final analysis (excluding six patients) based on split-body design between Group I (comprising 34 limbs which received 20 mL of 0.5% ropivacaine) and Group II (comprising 34 limbs which received 10 mL of 0.5% ropivacaine), baseline demographic data were collected. Length of the limb from anterior superior iliac spine (ASIS) to the base of the patella was comparable between two groups: Group I (in cm; 149 ± 1.63) versus Group II (in cm; 149.5 ± 1.51) ( Conclusion: 10 mL of 0.5% ropivacaine is noninferior to 20 mL of 0.5% ropivacaine in providing postoperative analgesia with preserved quadriceps muscle strength.
