Postoperative analgesia comparing levobupivacaine and ropivacaine for brachial plexus block: A randomized prospective trial.
Trial report in Medicine, 2017. 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
backgroundOn a pharmacologic basis, levobupivacaine is expected to last longer than ropivacaine. However, most reports of these anesthetics for brachial plexus block do not suggest a difference in analgesic effect. The aim of this study is to compare the postoperative analgesic effects of levobupivacaine and ropivacaine when used for treating ultrasound-guided brachial plexus block.
methodsA total of 62 patients undergoing orthopedic surgery procedures were prospectively enrolled and randomized to receive levobupivacaine (group L, N = 31) or ropivacaine (group R, N = 31). The duration of analgesia, offset time of motor block, need for rescue analgesics, and sleep disturbance on the night of surgery were recorded. Pain score was recorded on the day of surgery, and on postoperative days 1 and 2.
resultsThere was no difference in the time interval until the first request for pain medication comparing the two groups (group L: 15.6 [11.4, 16.8] hours; group R: 12.5 [9.4, 16.0] hours, P = 0.32). There was no difference in the duration of motor block (group L: 12.2 [7.6, 14.4] hours; group R: 9.4 [7.9, 13.2] hours, P = 0.44), pain score (P = 0.92), need for rescue analgesics (group L: 55%; group R: 65%, P = 0.6), or rate of sleep disturbance (group L: 61%, group R: 58%, P = 1.0) on comparing the two groups.
conclusionsThere was no difference in postoperative analgesia comparing levobupivacaine and ropivacaine when used for brachial plexus block.
