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

Lifestyle modifications to reduce risk factors for cardiovascular diseases such as blood pressure (BP) and smoking have been emphasized. Fruits and vegetables may modify such risk factors. The major aim of this randomized, controlled trial was to investigate the effects of (1) kiwifruits and (2) an antioxidant-rich diet compared with (3) a control group on BP and platelet aggregation (that is, whole-blood platelet aggregation) after 8 weeks in male smokers (age 44-74 years, n=102). The kiwifruit group received 3 kiwifruits per day, whereas the antioxidant-rich diet group received a comprehensive combination of antioxidant-rich foods. In the kiwifruit group, reductions of 10 mm Hg in systolic BP and 9 mm Hg in diastolic BP were observed (P=0.019 and P=0.016 (change from baseline in the kiwifruit group compared with change from baseline in the control group)). In the antioxidant-rich diet group, a reduction of 10 mm Hg in systolic BP was observed among hypertensives (P=0.045). Additionally, a 15% reduction in platelet aggregation and an 11% reduction in angiotensin-converting enzyme activity was observed in the kiwifruit group (P=0.009 and P=0.034). No effects on these parameters were observed in the antioxidant-rich diet group. This study suggest that intake of kiwifruit may have beneficial effects on BP and platelet aggregation in male smokers.
