Comparison of adductor canal block with periarticular infiltration analgesia in total knee arthroplasty: A meta-analysis of randomized controlled trials.

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
backgroundTotal knee arthroplasty (TKA) is accompanied by moderate to severe postoperative pain. Multimodal analgesia, such as femoral nerve block, periarticular infiltration analgesia (PIA), and patient-controlled intravenous analgesia, have been used for postoperative analgesia. Recently, randomized controlled trials have compared the efficacy of the adductor canal block (ACB) and the PIA in patients undergoing TKA. However, there is no definite answer as to the efficacy and safety of the ACB compared with the PIA.
methodRandomized controlled trials about relevant studies were searched from PubMed (1996 to May 2019), Embase (1980 to May 2019), and Cochrane Library (CENTRAL, May 2019). Five studies which compared the ACB with the PIA methods were included in our meta-analysis.
resultsFive studies containing 413 patients met the inclusion criteria. There were no significant differences between the ACB and the PIA group in visual analog scale (VAS) score at rest (P = .14) and movement (P = .18), quadriceps muscle strength (P = .95), complications (P = .78), length of stay (LOS) (P = .54), and time up and go (TUG) test (P = .09), While patients in the ACB group had less equivalent morphine consumption (P < .05) compared with the PIA group.
conclusionsOur pooled data indicated the ACB group reduced the equivalent morphine consumption compared with the PIA group, with no statistically significant differences in the VAS score, quadriceps muscle strength, TUG test, complications, and LOS.
