Study Protocol for Feasibility Randomized, Placebo-Controlled Trial of Efficacy of Midazolam as the Second-Line Treatment for Dyspnea in Patients with Advanced Cancer.
Article in Palliative medicine reports. 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
Background: Dyspnea is one of the most distressing symptoms in patients with advanced cancer. Although systemic opioids are recommended as first-line pharmacologic treatment, 30-50% of patients do not achieve adequate relief. Midazolam is often used for persistent dyspnea despite opioid administration; however, robust evidence supporting its efficacy as a second-line treatment remains limited. Objectives: To evaluate the feasibility of a randomized controlled trial assessing the efficacy and safety of continuous subcutaneous midazolam infusion as second-line treatment for persistent dyspnea despite morphine administration in hospitalized patients with advanced cancer. Methods: A protocol for a multicenter, randomized, double-blind, placebo-controlled feasibility trial (J-SUPPORT2201/JORTC-PAL22) is described. The trial is being conducted at nine sites in Japan. Population: Participants are hospitalized adult patients with advanced cancer who are not receiving active anticancer treatment and who experience dyspnea at rest (Integrated Palliative Care Outcome Scale dyspnea score ≥2) despite continuous morphine infusion. Intervention/Control: Protocol treatment includes standardized morphine escalation plus continuous subcutaneous infusion of midazolam (9 or 6 mg/day for vulnerable patients) or placebo for 24 hours. Measurements: The primary endpoint is feasibility, defined as completion of protocol treatment at 24 hours. Secondary endpoints include dyspnea intensity, anxiety, rescue morphine use, communication, adverse events, and 30-day survival. Conclusions: This feasibility trial will provide methodological insights and preliminary clinical data regarding midazolam as a second-line option for persistent dyspnea despite morphine infusion in patients with advanced cancer and help design future confirmatory trials.
