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

objectivesSeveral studies have reported the potential association between smoking and diabetic nephropathy. However, the studies of non-significant association results were against the association between smoking and diabetic nephropathy. Therefore, the relationship between smoking and diabetic nephropathy was still debated and controversial.

methodsProspective cohort studies were included in the current meta-analysis. The tobacco smoking (current smokers or former smokers) and non-smoking groups in the enrolled studies were compared for the hazard ratio (HR) of diabetic nephropathy. Fifteen studies with 221,821 subjects were included in this meta-analysis. Subgroup analysis of the type 1 diabetes and type 2 diabetes groups was also performed individually to investigate the effects of different types of diabetes on the relationship between smoking and diabetic nephropathy.

resultsCurrent smoking was significantly associated with a greater log HR of diabetic nephropathy [1.44 (1.22-1.70), Z = 4.39]. In addition, former smoking was significantly associated with diabetic nephropathy [log HR = 1.04 (1.03-1.05), Z = 8.02]. The individual subgroup analysis of type 1 diabetes and type 2 diabetes subjects showed that smoking might be both significantly associated with greater log HRs of diabetic nephropathy. DISCUSSION: Current and former smoking might be the risk factors for diabetic nephropathy in the current meta-analytic results. The phenomenon of such significant associations were discovered in type 1 and 2 diabetes.
