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

objectiveTo determine whether omega-3 fatty acid (FA) increases the natural log of very low frequency (lnVLF) power, an index of heart rate variability (HRV), and reduces 24-hour heart rate (HR) in depressed patients with coronary heart disease (CHD). Low intake of omega-3 FAs is associated with depression and with low HRV, and all three are associated with an increased risk of death in patients with CHD.

methodsThirty-six depressed patients with CHD randomized to receive 50 mg of sertraline and 2 g of omega-3/day, and 36 randomized to sertraline and a placebo, had 24-hour HRV measured at baseline and after 10 weeks of treatment.

resultsThere was a significant treatment × time interaction for covariate adjusted lnVLF (p = .009), for mean 24-hour HR (p = .03), and for 1-minute resting HR (p = .02). The interaction was not significant for three other measures of HRV. LnVLF did not change over time in the omega-3 arm but decreased in the placebo arm (p = .002), suggesting that omega-3 may have prevented or slowed deterioration in cardiac autonomic function.

conclusionsThe effects of omega-3 FAs on lnVLF and HR, although modest, were detected after only 10 weeks of treatment with 2 g per day of omega-3. Whether a longer course of treatment or a higher dose of omega-3 would further decrease HR, improve other indices of HRV, or reduce mortality in depressed CHD patients should be investigated.
