The effect of lavender aromatherapy and acetaminophen as preemptive on comfort and Nitroglycerin-induced headache in acute coronary syndrome.

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
backgroundNitroglycerin (NTG) improves cardiac ischemia, but one of its side effects is headache. This study aimed to compare the effects of lavender aromatherapy and acetaminophen as preemptive interventions on comfort and NTG-induced headache in patients with acute coronary syndrome (ACS).
methodsThis three-arm randomized clinical trial was conducted on 90 patients divided into three groups of 30. In the acetaminophen group, patients were given 500 mg of oral acetaminophen approximately 15 minutes before IV nitroglycerin infusion. In the lavender group, 15 minutes before nitroglycerin IV infusion, cotton gauze soaked in three drops of 2% lavender essential oil was used. In the control group, patients received routine care for the treatment of NTG-induced headaches. The severity of patients' headaches was evaluated using the visual analog scale (VAS) at 5, 10, 15, and 60 minutes after starting nitroglycerin infusion.
resultsThe mean headache intensity at the 60th minute in the lavender and control groups was 1.37 ± 1.10 and 2.50 ± 2.43, respectively, while no headaches were reported in the acetaminophen group. The highest mean pain severity recorded at different times was 2.12 ± 0.86 in the control group. Headache severity varied across the intervention minutes among the three groups (p < 0.001). Additionally, post-intervention comfort was significantly higher in the acetaminophen and lavender groups compared to the control group (p < 0.001), with a significant difference observed between the groups (p < 0.001).
conclusionThe results of this study suggest that acetaminophen can be used as a preemptive agent to reduce NTG-induced headaches and improve the comfort of ACS patients.
