Pregabalin for chronic cough due to lung cancer: randomized, double-blind, placebo-controlled trial.
Trial report in British journal of cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundDeveloping effective therapies for cough in lung cancer is an unmet need Neuromodulators like pregabalin may act centrally as cough suppressants.
methodsRandomized double-blind placebo-controlled study in patients with locally advanced/metastatic lung cancer and at least 2 weeks of moderate or severe cough. Randomization was 1:1 to pregabalin 300 mg orally daily or matching placebo, both administered for 9 weeks. Primary endpoint was the change in cough severity as measured by the difference in VAS scores.
resultsBetween Jul 2022 and Dec 2023, we enrolled 166 patients: 83 to each arm. Baseline cough severity was grade 2 in 128 (77.1%) and grade 3 in 38 (22.9%) patients; median cough duration was 12 weeks (IQR, 6-20). Systemic cancer-directed therapy was started in 78 (94.0%) and 72 (86.7%) patients in the pregabalin and placebo arms, respectively; P = 0.187. The mean (SD) VAS score (in mm) decreased from 71.58 (14.99) at baseline, to 45.54 (26.60) on day 7, and 22.27 (24.20) by week 9 in the pregabalin arm; and 71.75 (17.58), 46.35 (25.00), and 23.08 (22.42), respectively in the placebo arm; P = 0.877.
conclusionPregabalin does not significantly decrease cough in patients with lung cancer. Systemic cancer-directed therapy is the most effective antitussive. CLINICAL
