Study on the Effect of Different Doses of Hydromorphone on the Time Response and Postoperative Analgesia of Ropivacaine in Ultrasound-Guided Suprailiac Fascia Inguinal Block.
Article in Evidence-based complementary and alternative medicine : eCAM, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 2 papers.
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
objectiveTo investigate the effects of different doses of hydromorphone under the guidance of ultrasound on ropivacaine blocking the superior inguinal iliac fascia and postoperative analgesia.
methodsFrom January 2020 to June 2021, 90 American Society of Anesthesiologists (ASA) I-II patients undergoing elective total hip arthroplasty (THA) were selected and randomly divided into 3 groups, 30 patients in each one. Ultrasound-guided superior inguinal iliac fascia block was performed in the patients of the 3 groups before operation. The L group: 0.3% ropivacaine 30 ml; the H1 group: 0.3% ropivacaine + 25
resultsThe time from the end of surgery to the appearance of pain in the H2 group was higher than that in the H1 group and the L group, and the time in the H1 group was higher than that in the L group (
