Analgesic Effect of Preoperative Intravenous Administration of Paracetamol on Post-cesarean Pain: A Randomized Clinical Trial.

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: Pain control after every surgery, especially cesarean section, is very important, and physicians strive to discover pain control methods using the least amount of opioids. Paracetamol is a non-opioid analgesic with few complications. Objectives: The present study aimed to investigate the analgesic effect of preoperative intravenous administration of paracetamol on post-cesarean pain. Methods: This randomized, double-blind clinical trial was conducted on 240 pregnant women under spinal anesthesia who were candidates for elective cesarean section. The patients' weight, height, age, and body mass index (BMI) were recorded, and patients were randomly divided into 2 equal groups (n = 120). In the first group, 10 mg/kg paracetamol in 100 mL of normal saline (paracetamol group) and, in the second group, 100 mL normal saline (control group) were administered 15 minutes before surgery intravenously. Blood pressure, pulse rate, chills, and nausea were recorded during and 1 hour after surgery; in addition, the visual analogue scale (VAS) and the need for additional analgesics were recorded 1, 2, 4, 6, 12, and 24 hours after surgery. Results: Mean pain scores were significantly lower in the paracetamol group (4.01 ± 2.22) than in the control group 6 hours (4.83 ± 2.35; P = 0.008) and 24 hours (2.26 ± 1.85 and 2.67 ± 1.80, respectably; P = 0.038) after surgery. Mean meperidine consumption was lower in the paracetamol group than in the control group, but it was not significant. No significant difference was found between the 2 groups in the frequency of chills and nausea (P > 0.05). Conclusions: Within the limitations of the current study, preoperative intravenous administration of paracetamol significantly reduced post-cesarean pain within 24 hours.
