Correcting zinc deficiency in nursing home residents: a randomized trial comparing 30 and 60 mg/day elemental zinc supplementation.
Trial report in Frontiers in nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05527899 (Zinc Intervention in Elderly for Prevention of Pneumonia), which is not on this 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.

Abstract
Introduction: Low serum zinc is associated with higher pneumonia incidence and illness duration compared to individuals with adequate serum zinc levels. However, the optimal and safe zinc supplementation dose to correct deficiency has not been established. This study aimed to determine the optimal and safe dose of elemental zinc supplementation to correct deficiency in older adults residing in nursing homes. Methods: Methods: We conducted a 12-month randomized, placebo-controlled, double-blind clinical trial in zinc-deficient nursing home residents, comparing supplementation of 30 and 60 mg/day elemental zinc versus placebo on zinc status and potential adverse effects (n = 26-35/group). Results: Both the 30 and 60 mg/day groups significantly increased serum zinc levels compared to placebo ( Discussion: In zinc deficient older adults, 60 mg/day of elemental zinc effectively corrected deficiency with no adverse effects. These findings inform the dosing protocol for a fully powered randomized trial testing the effect of zinc supplementation on pneumonia incidence and outcomes in this population.
