Potential Therapeutic Synergy of High-Dose Vitamin C and Nicotinamide as Adjunctive Therapy in an Elderly Patient With Extensive-Stage Small-Cell Lung Cancer: A Case Report.
Article in Cureus, 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
We report the case of a 78-year-old male with extensive-stage small-cell lung cancer (ES-SCLC) involving the brain, bone, and adrenal gland at diagnosis, who exhibited a near-complete thoracic radiologic response following platinum-etoposide-atezolizumab therapy with consolidative thoracic and whole-brain radiotherapy. In addition to standard chemoimmunotherapy, the patient self-administered high-dose oral vitamin C (3g/day) and nicotinamide (3g/day) continuously throughout treatment, raising the possibility that metabolic adjunctive therapy may have contributed to the depth of response. Initial CT and fluoro-ethyl-tyrosine (FET) fusion imaging showed a large mediastinal mass, which nearly disappeared after five cycles of treatment. This case highlights that substantial therapeutic responses are achievable even in elderly patients with extensive metastatic disease and suggests that adjunctive metabolic modulation with high-dose vitamin supplementation may warrant further investigation as a potential enhancer of response to chemoimmunotherapy.
