1 · What the graph read from it

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.

2 · The registry

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

objectiveWe prospectively evaluated the haptoglobin (Hp)-stroke association in type 1 diabetes and hypothesized that despite increasing the risk of coronary artery disease, the presence of the Hp 2 allele would be associated with a lower incidence of stroke.

methodsParticipants from the Epidemiology of Diabetes Complications study without prevalent stroke and Hp available were evaluated (n = 607; mean age 27.6 years and duration 19.3 years).

resultsDuring 22 years of follow-up, stroke incidence did not differ by Hp genotype (p = 0.49). Restricting analyses to those diagnosed with diabetes ≥1965 (13% mortality vs 40% in the <1965 cohort) to diminish potential survival bias, the adjusted hazard ratio (HR) for Hp 1-1 was 3.08 (95% confidence interval (CI) = 0.81-11.77, p = 0.10). Further stratifying by hypertension prevalence, an increased stroke incidence was observed with Hp 1-1 only in those with hypertension (HR = 7.03, 95% CI = 1.42-34.89, p = 0.02).

conclusionDespite the protective effect against vascular diabetes complications, a borderline increased risk of stroke was observed with Hp 1-1 in type 1 diabetes. This mixed Hp effect on cardiovascular risk by outcome studied merits further investigation and cautions against the universal application of preventive therapies across all Hp genotypes.
