A randomized comparative evaluation of local infiltration analgesia, extended nerve blocks, and conventional analgesia in pain management after total knee arthroplasty.
Trial report in Joint diseases and related surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
objectivesThe aim of this study was to analyze the postoperative effects of extended nerve blocks and local infiltration analgesia (LIA) on postoperative pain control, muscle weakness, and blood loss after total knee arthroplasty (TKA). PATIENTS AND
methodsBetween February 24
resultsThe pain was maximal between 4 and 8 h postoperatively, when the effect of the spinal anesthetic drugs disappeared. During this critical period, tolerable pain (Numerical Rating Scale, NRS ≤3) was observed in 52%, 42%, and 19% of nerve blockade in LIA and control groups, respectively. None of the patients complained of high-intensity pain (NRS >8) in the LIA group, which was a significant difference from the block and control groups (10% and 14%, p<0.008, respectively). There was no significant muscle weakness associated with the use of this extended block. The decrease in hemoglobin level was significantly lower in the LIA group than in the control and block groups (odds ratio [OR]: 0.379, 95% confidence interval [CI]: 0.165-0.874 for nerve blockade vs. LIA, OR: 1.189, 95% CI: 0.491-2.880 for nerve blockade vs. control, OR: 0.319, 95% CI: 0.140-0.727, respectively). The common language effect size for pain in each referred interval in each group and for decrease of hemoglobin between the first and third postoperative days fell between 0.507 and 0.680.
conclusionThis study demonstrates that LIA technique offers a fast and safe treatment option for pain relief after TKA. No clinically relevant muscle weakness was observed among groups according to field block applications. Significant advantages were also achieved in blood loss.
