Continuous adductor canal block following total knee arthroplasty provides a better analgesia compared to single shot: A prospective randomized controlled trial.
Trial report in Acta orthopaedica et traumatologica turcica, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05956275 (Comparison Between USG-Guided Infiltration Popliteal Artery Capsule Knee Block Versus Adductor Canal Block Application as Postoperative Analgesia in Total Knee Prosthesis Under General Anesthesia), which is not on this map.

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.

Abstract
objectiveThe aim of this study was to compare single-shot adductor canal block and continuous infusion adductor canal block techniques in total knee arthroplasty patients.
methodsWe prospectively randomized 123 patients who were scheduled for unilateral primary total knee arthroplasty surgery into single shot (n = 60; mean age: 67.1 ± 6.9 years) and continuous (n = 63; mean age: 66.9 ± 6.8 years) adductor canal block groups. Postoperative visual analog scale pain scores, need for additional opioids and functional results as; timed up and go test, the 30-s chair stand test, 5 times sit-to-stand test, the 6-min walking test, the time to active straight leg raise, time to walking upstairs, maximal flexion at the time of discharge, duration of stay in hospital were compared between the two groups.
resultsPain scores were lower in the continuous adductor canal block group as compared to the single-shot adductor canal block group throughout the postoperative period (p = 0.001). Rescue analgesia was required for 6 (10%) patients in the single shot group and for 1 (1.59%) patient in the continuous group (p = 0.044). Patients in the continuous adductor canal block group displayed better functional results than the single-shot adductor canal block group with respect to active straight-leg rise time (25.52 ± 4.56 h vs 30.47 ± 8.07 h, p = 0.001), 6-min walking test (74.52 ± 29.38 m vs 62.18 ± 33.32 m, p = 0.035) and maximal knee flexion degree at discharge (104.92 ± 5.35° vs 98.5 ± 7.55°, p = 0.001). There was no significant difference between the two groups for other functional and ambulation scores.
conclusionPain control following total knee arthroplasty was found to be better in those patients treated with continuous adductor canal block as compared to those treated with single-shot adductor canal block. Patients treated with continuous adductor canal block also displayed better ambulation and functional recovery following total knee arthroplasty. LEVEL OF EVIDENCE: Level I, Therapeutic Study.
