Efficacy of Olanzapine 5 mg versus 10 mg for the Prophylaxis of Chemotherapy-Induced Nausea and Vomiting in Patients Receiving High Emetic Risk Chemotherapy without Neurokinin-1 Receptor Antagonist.
Trial report in Asian Pacific journal of cancer prevention : APJCP, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 3 of them syntheses 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
objectiveTo compare the efficacy and safety of two different dosage levels of olanzapine for the prevention of chemotherapy-induced nausea and vomiting (CINV) in patients receiving high emetic risk chemotherapy.
methodsThis study was a randomized, double-blind, controlled trial designed to show non-inferiority in the efficacy of olanzapine 5 mg compared to 10 mg in patients treated with high dose cisplatin or doxorubicin/cyclophosphamide. Non-inferiority was defined as a lower margin of the 95% confidence interval (95% CI) that not lower than the margin set at -25%.
resultA total of 140 patients were randomized to 5 mg group (n=70) or 10 mg group (n=70) of olanzapine. The complete response (CR) rate in the overall phase of olanzapine 5 and 10 mg was 58.6% v 62.9% (95%CI: -20.4, 11.8). The CR rate comparison between olanzapine 5 and 10 mg was 81.4% v 74.3% (95%CI: -6-6, 20.8) and 66.7% v 76.1% (95%CI: -23.5, 6.3) for the acute and delayed phase, respectively. No nausea rates in acute, delayed and overall phase were 70.0% v 68.6% (95%CI: -13.8, 16.6), 45.7% v 48.6% (95%CI: -19.4, 13.6) and 43.5% v 47.9% (95%CI: -19.2, 13.6). The rate of adverse events (AE) including somnolence were not different between the 5 and 10 mg groups.
conclusionThe two dosage levels of olanzapine were not different in terms of the efficacy and AE in the prophylaxis of CINV.
