Aromatherapy Improves Pain, Sleep and Physiological Parameters in Laparoscopic Cholecystectomy Patients: A Single-Blind, Parallel Group, and Randomized Controlled Trial.
Trial report in Chinese journal of integrative medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05464602 (The Effect of Aromatherapy on Postoperative Pain, Sleep Quality and Physiological Parameters in Laparoscopic Cholecystectomy Patients), which is not on this 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.

Abstract
objectiveTo investigate the effects of inhaled lavender and geranium essential oils on pain, sleep and physiological parameters in patients who underwent laparoscopic cholecystectomy.
methodsThis is a randomized controlled study with a single-blind parallel group. A total of 153 patients were assigned to 3 groups, including control, lavender, and geranium groups, with 51 patients in each group by a stratified block randomization method. Inhalation aromatherapy with lavender and geranium essential oil was administered to 2 intervention groups, respectively. Patients in the control group only recelved standard treatment. Physiological parameters, pain intensity, and sleep quality were recorded before surgery, the day of surgery, and one day after surgery.
resultsThere was no significant difference in the pain intensity among 3 groups before aromatic oil inhalation (P>0.05). A significant decrease in the pain intensity was observed in the patients with aroma inhalation after surgery compared with the control group (P<0.01). A higher increase in sleep quality was observed in the geranium group compared with the lavender group (P<0.01). There was a significant difference within the groups in terms of physiological parameters (P<0.05). Moreover, a significant weak correlation was observed between the frequency of analgesic use and pain intensity on the first postoperative day in the lavender group (r=-0.297, P=0.034), and between the frequency of analgesic use and postoperative sleep quality in the geranium group (r=0.297, P=0.034).
conclusionInhalation aromatherapy with lavender and geranium essential oils in patients who underwent laparoscopic cholecystectomy decreases pain intensity, increases sleep quality, and stabilizes physical parameters in the preoperative and postoperative periods. (Registration No. NCT05464602).
