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

objectiveTelomere shortening has been seen in major psychiatric disorders, including major depressive disorder. However, only a few small studies have examined this in bipolar disorder (BD). We compared the telomere length in patients with BD1 or BD2 with that in matched healthy controls.

methodsWe included 215 patients with BD (128 BD1, 87 BD2) and 204 age- and sex-matched healthy controls. Relative telomere length was determined by quantitative polymerase chain reaction. The patients and controls were compared separately for age groups, sex, and BD subgroups (BD1 and BD2).

resultsWe found significant telomere shortening in patients with BD1 (p < 0.001), but not in patients with BD2. In male patients with BD1, the 30-39 year age group had significant shortening of telomere length than controls (p = 0.01). Female patients with BD1 in the 19-29-year age group had significantly shortened telomeres compared to the controls (p < 0.01).

conclusionOur results suggest a significant reduction in telomere length in BD1. Telomere shortening would be a potential biomarker for BD.
