Single shot versus continuous technique adductor canal block for analgesia following total knee arthroplasty: A PRISMA-compliant meta-analysis.
Synthesis in Medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 2 of them syntheses 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
backgroundAn adductor canal block (ACB) provides recognized analgesia following total knee arthroplasty (TKA). This meta-analysis compared the single-injection ACB (SACB) with the continuous-injection ACB (CACB).
methodRelevant studies were searched from PubMed (1996-October 2018), Embase (1980-October 2018), and Cochrane Library (CENTRAL, October 2018). Four randomized controlled trials (RCTs), which compared SACB with CACB, were included in our meta-analysis.
resultsFour RCTs met the inclusion criteria. Our pooled data indicated that the SACB group had similar efficacy compared with the CACB group in terms of morphine consumption (P = .19), time to first opioid request (P = .32), range of motion (P = .97), and visual analogue scale (VAS) scores at 24 hours at rest (P = .12) and movement (P = .24), without increasing the risk of complications (P = .97) and length of stay (P = .54).
conclusionThe SACB technique provides similar analgesia in the 24 hours following TKA compared with CACB, while the CACB method was better over 48 hours.
