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

background25-hydroxyvitamin D [25(OH)D] concentrations and physical activity (PA) are linked and both are associated with changes in mortality. We examined the association of 25(OH)D and PA with all-cause or cause-specific mortality risk in stroke survivors.

methodsThe analysis included 677 stroke survivors from National Health and Nutrition Examination Survey (NHANES) 2007-2008 to 2017-2018. Independent and joint associations of 25(OH)D, PA and mortality among stroke survivors were analyzed using weighted Cox regression.

resultsWe identified 133 all-cause deaths [major adverse cardiovascular events (MACE), 34; non-MACE, 79] with a median follow-up of 5.8 years (interquartile, 2.8-8.9 years). In a range of adjusted models, high 25(OH)D was observed with lower all-cause mortality compared to low 25(OH)D (HR, 0.376; 95% CI, 0.233-0.607) and non-MACE (HR, 0.265; 95% CI, 0.143-0.490) mortality was consistently associated. At the same time, compared with no PA, PA was associated with a lower all-cause (HR, 0.280; 95%CI, 0.107-0.733) and non-MACE (HR, 0.266; 95%CI, 0.087-0.810) was associated with a lower risk of death. In addition, pooled analyses showed that stroke survivors with high 25(OH)D and PA had the lowest risk of all-cause death (HR, 0.132; 95%CI, 0.038-0.460) and non-MACE (HR, 0.092; 95%CI, 0.023-0.363), there is an additive interaction between 25(OH)D and PA in non-MACE.

conclusionIn conclusion, this study found that combining high 25(OH)D levels and PA showed an enhanced protective effect which demonstrated a synergistic effect between them in reducing mortality among stroke survivors. These findings provide new ideas and possibilities for the prevention and treatment of cardiovascular and cerebrovascular diseases, offering a reference for development of clinical practice guidelines in the future.
