[Comparison of palonosetron-dexamethasone and ondansetron-dexamethasone for prevention of postoperative nausea and vomiting in middle ear surgery: a randomized clinical trial].
Trial report in Brazilian journal of anesthesiology (Elsevier). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis 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
backgroundPostoperative nausea and vomiting is the second most common complaint in the postoperative period after pain. The incidence of postoperative nausea and vomiting was 60-80% in middle ear surgeries in the absence of antiemetic prophylaxis. Because of this high incidence of postoperative nausea and vomiting, we aimed to assess the effect of palonosetron-dexamethasone and ondansetron-dexamethasone combination for the prevention of postoperative nausea and vomiting in patients of middle ear surgery.
methodsSixty-four patients, scheduled for middle ear surgery, were randomized into two groups to receive the palonosetron-dexamethasone and ondansetron-dexamethasone combination intravenously before induction of anesthesia. Anesthesia technique was standardized in all patients. Postoperatively, the incidences and severity of nausea and vomiting, the requirement of rescue antiemetic, side effects and patient satisfaction score were recorded.
resultsDemographics were similar in the study groups. The incidence difference of nausea was statistically significant between groups O and P at a time interval of 2-6hours only (p=0.026). The incidence and severity of vomiting were not statistically significant between groups O and P during the whole study period. The overall incidence of postoperative nausea and vomiting (0-24hours postoperatively) was 37.5% in group O and 9.4% in group P (p=0.016). Absolute risk reduction with palonosetron-dexamethasone was 28%, the relative risk reduction was 75%, and the number-needed-to-treat was 4. The patient's satisfaction score was higher in group P than group O (p=0.016). The frequency of rescue medication was more common in group O than in group P patients (p=0.026).
conclusionThe combination of palonosetron-dexamethasone is superior to ondansetron-dexamethasone for the prevention of postoperative nausea and vomiting after middle ear surgeries.
