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: Effective pain management is crucial in septorhinoplasty and remains a significant challenge. This study investigated the effect of ketorolac and paracetamol on pain control in septorhinoplasty patients and assessed their efficacy in reducing the need for rescue analgesics. Methods: This double-blind randomized clinical trial was conducted at Madar-Koodak Hospital (Shiraz, Iran), in 2022. Ninety-nine patients were randomly assigned to three groups to receive ketorolac 30 mg (n=33), paracetamol 1000 mg (n=33), and normal saline (n=33), respectively. All the medications were administered intravenously (IV) 30 min before surgery. The randomization procedure followed the block randomization method. If the pain did not subside, patients were also given a single dose of pethidine hydrochloride (25 mg). Pain intensity was measured using visual analog scale (VAS) 1 hour and 6 hours after surgery. The data were analyzed using SPSS software, using paired Results: One-hour post-surgery, VAS scores in the ketorolac and paracetamol groups were significantly lower than in the placebo group (P<0.001). The mean difference with 95% CI for ketorolac-placebo and paracetamol-placebo was -0.57 (-0.94, -0.21), and -0.79 (-1.12, -0.45), respectively. The ketorolac and paracetamol groups required significantly less pethidine hydrochloride 1 hour post-surgery than the placebo group (P<0.001). The VAS scores and requiring pethidine were not significantly different between the ketorolac and paracetamol groups. Conclusion: After septorhinoplasty, the administration of 1000 mg of IV paracetamol demonstrated comparable efficacy in pain reduction to 30 mg of ketorolac. It suggested that paracetamol could serve as a viable alternative to ketorolac in preventing postoperative pain after septorhinoplasty, particularly in patients for whom non-steroidal anti-inflammatory (NSAID) drugs could not be a suitable choice.
