Randomized Controlled Trial to Relieve Pain of Chemotherapy-Induced Peripheral Neuropathy by Magnetic Field: SMILE Study.
Article in Cancers, 2026. 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/
objectivesChemotherapy-induced peripheral neuropathy (CIPN) is a common side effect of taxanes and platinum-based agents, impairing quality of life. Duloxetine is the only drug with proven efficacy, but is often limited by tolerability. AT-04 is a portable alternating magnetic field device that activates descending pain modulatory systems and has shown safety in other pain settings. This investigator-initiated trial evaluated the efficacy and safety of AT-04 for persistent CIPN.
methodsWe conducted a randomized, double-blind, sham-controlled, multicenter phase II study. Patients with CIPN lasting ≥12 weeks after chemotherapy and pain NRS ≥ 4 were enrolled. Participants used AT-04 or sham devices twice daily for 12 weeks. The primary endpoint was the change in pain NRS on day 85. Secondary endpoints included tingling NRS, numbness NRS, CIPN20 subscales, and safety.
resultsTwenty-eight patients were randomized (14 per arm). No significant difference was observed in pain NRS on day 85 {AT-04: -1.74 ± 0.6 vs. sham device: -1.45 ± 0.6; one-sided
conclusionsAT-04 did not significantly reduce pain NRS but improved motor function in CIPN patients, especially in those >1 year after chemotherapy. AT-04 may be a promising non-pharmacological option; larger confirmatory trials are required.
