Exploring the Efficacy and Safety of Ketamine for Managing Acute Renal Colic in Emergency Departments: A Systematic Review of Recent Clinical Trials.
Synthesis in International journal of molecular sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Kidney stones typically present as renal colic in emergency departments (EDs), where patients experience severe pain and often require parenteral therapy for symptom management. The economic burden associated with managing kidney stones exceeds USD 5 billion annually in the US and accounts for more than a million visits to EDs each year. There is clear evidence emphasizing the need for innovative and alternative pain control options for patients with renal colic. Recent randomized controlled trials suggest that intranasal (IN) and intravenous (IV) ketamine are as effective as parenteral NSAIDs and opioids in treating renal colic. However, the limited studies available show inconsistent results regarding the analgesic effects of ketamine. In this study, we reviewed the mechanism of action of ketamine for kidney stones, its efficacy in treating acute renal colic, and the potential adverse side effects of ketamine treatment. A population, intervention, comparison, and outcome (PICO)-related question was formulated to guide our research inquiry: "What are the effects of IV or IN ketamine, as a single agent or as an adjuvant (I), in adult patients diagnosed with acute renal colic (P) on pain scale scores and adverse side effects (O) compared to NSAIDs and/or opioids (C)?"
