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

introductionNarcissism has been studied for its role in leadership using various versions of the Narcissistic Personality Inventory (NPI). Narcissism is described as having a "dark and negative" side as well as a "positive or bright" side. The bright side of narcissism, in particular, has been studied for its role in leadership. In studies among military personnel in Finland and Hungary, the NPI has been associated with positive leadership traits. We assessed if measures of narcissistic personality were predictive of entrance to and graduation from the Army Ranger Course among United States (U.S.) Army personnel. MATERIALS AND

methodsWe included the NPI as one of the measures in the Ranger Resilience and Improved Performance on Phospholipid-bound Omega-3's (RRIPP-3) study. RRIPP-3 was a double-blind, placebo-controlled dietary supplement intervention trial at Fort Benning, GA, that enrolled 555 officers when they entered the U.S. Army Infantry Basic Officer Leadership Course (IBOLC) with the intention to complete the U.S. Ranger School. RRIPP-3 volunteer participants consumed eight dietary supplements daily containing 2.3 g of omega-3 (krill oil) or macadamia nut oil (control) over a 20-week period. Blood spot samples were collected to monitor intake compliance. Cognitive functioning, resilience, and mood were assessed at approximately 14 and 16 weeks. Dietary intake was also assessed. The 40-item, forced-choice NPI was included to assess if three factors of narcissism: Leadership/Authority, Grandiose/Exhibitionism, and Entitlement/Exploitativeness measures of narcissistic personality were associated with entrance to and graduation from the Army Ranger Course.

resultsOf the 555 soldiers enrolled in RRIPP-3, there were no statistically significant differences in the total NPI scores comparing U.S. Army IBOLC officers who enrolled (n = 225) versus did not enroll (n = 330, p = .649) or graduated (n = 95; versus did not graduate [n = 460, p = .451]) from the Ranger Course. None of the three-factor NPI subscales differed statistically comparing either enrollment in (p = .442, .510, and .589, respectively) or graduation from the Ranger Course (p = .814, .508, and .813, respectively).

conclusionsAlthough narcissism has been positively associated with military trainee success in other countries, we did not find an association between narcissism and trainee success among U.S. Army trainees, and accordingly the level of narcissism did not predict trainee success or failure.
