[Comparison between subarachnoid morphine and femoral nerve block for analgesia after knee ligament reconstruction: a randomized clinical trial].
Trial report in Brazilian journal of anesthesiology (Elsevier). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND AND
objectivesThere is no consensus of the ideal technique to provide analgesia in knee ligament reconstructions. The aim of this study was to compare the intensity of postoperative pain in these patients under different modalities of analgesia.
methodRandomized and controlled clinical trial of patients undergoing reconstruction of the anterior cruciate ligament (ACL) with flexor tendons between December 2013 and 2014. All patients underwent spinal anesthesia and rescue analgesia with tramadol. The Groups C, M, R0,375 and R0,25 were compared with only the previously described technique, subarachnoid morphine (100 μg) or femoral nerve block with 25 mL of 0.375% ropivacaine and 0.25%, respectively. Pain intensity at 6, 12 and 24hours, age, sex, rescue analgesia, adverse reactions and satisfaction were evaluated.
resultsAmong the 83 eligible patients, a predominance of males (85.7%) was observed, between 28 and 31 years. The Group C requested more opioid (27.3%) than the other groups, without significance when compared. There were no significant differences in pain intensity at 6, 12 and 24hours. There was a higher incidence of urinary retention in the Group M (23.8%) than in the R0,375 (0%) and prolonged quadriceps motor block in the R0,375 Group (30%) than in the M and C Groups (0%), with statistical significance (p < 0.05).
conclusionThere was no difference in the intensity of postoperative pain in patients submitted to anterior cruciate ligament reconstruction with flexor tendons under the analgesic modalities evaluated, despite the predominance of urinary retention in the M Group and motor block in the R0,375 Group.
