Ultrasound-Guided Thoracic Paravertebral Block Enhances the Quality of Recovery After Modified Radical Mastectomy: A Randomized Controlled Trial.
Trial report in Journal of pain research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 3 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
purposeUltrasound-guided thoracic paravertebral block (TPVB) has become increasingly popular for postoperative analgesia after breast surgery. We designed this prospective, randomized, double-blind, placebo-controlled trial to test the hypothesis that TPVB is superior to placebo in improving the patient quality of recovery following modified radical mastectomy. PATIENTS AND
methodsSixty-eight female patients undergoing elective unilateral modified radical mastectomy were enrolled. Patients were randomized to receive preoperative ultrasound-guided TPVB with 0.5% ropivacaine (TPVB group, n=34) or 0.9% saline (Control group, n=34). The primary outcome was quality of recovery, measured 24 h after surgery using the 40-item Quality of recovery questionnaire (QoR-40). Secondary outcomes were the area under the curve of the visual analog scale pain scores over 24 h, postoperative 24-h morphine consumption, time to first rescue analgesia, length of post-anesthesia care unit stay, postoperative nausea and vomiting, and patient satisfaction.
resultsThe global QoR-40 score 24 h postoperatively (median [interquartile range]) was 173 [170-177] in the TPVB group and 161 [160-164] in the control group (
conclusionA single preoperative injection of TPVB with ropivacaine enhances the quality of recovery and postoperative analgesia in patients following modified radical mastectomy.
