Investigating the associations of glycemic load and glycemic index with lung cancer risk in the Southern Community Cohort Study.

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
purposeDiets with a high glycemic load (GL) or glycemic index (GI) may increase cancer risk. Findings from prior studies on the relationship between GL, GI, and lung cancer risk are inconsistent. We investigated this relationship in a large prospective cohort.
methodsWe analyzed data from the Southern Community Cohort Study, a prospective cohort that includes diverse racial groups predominantly low-income adults aged 40-79 in 12 southeastern states of the USA. We estimated dietary GL and GI values using data collected from food frequency questionnaires at baseline. Dietary GL and GI were energy adjusted by residual method and categorized into sex-specific quintiles. Cox proportional hazard regression was used to assess the associations between dietary GL, GI, and lung cancer risk. We further performed stratified analyses by various factors.
resultsIntakes of individual food items or food groups that commonly contribute to GL were similar between blacks and whites in the cohort. After excluding the first two years of follow-up, 947 incident lung cancers were ascertained among 55,068 participants. Neither dietary GL nor GI was significantly associated with incident lung cancer risk in the overall population (GL: Q5 vs. Q1, HR = 0.88, 95% CI 0.72-1.07, p
conclusionDietary GL and GI were not independently associated with incident lung cancer risk in a large understudied population.
