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

aimsThe prevalence of mitral valve prolapse (MVP) varies across populations and age groups; its natural history and clinical outcomes remain unclear. This meta-analysis established the prevalence of MVP in the general population, in associated syndromes and at different ages. It also determined the rate of progression and the incidence of adverse outcomes. METHODS AND

resultsA systematic search identified original reports on the prevalence of MVP and related outcomes. A total of 83 studies met inclusion: 47 (n = 992 944) non-syndrome associated; 31 (n = 3067) syndrome associated; and 5 (n = 1287) described mitral regurgitation (MR) progression or adverse outcomes. In the general population, the prevalence was 1.35% but higher in hospital cohorts (8.7%). Age-stratified prevalence was 0.5, 1.8, 2.7, and 2.0% in neonates, children, adolescents and adults, respectively. Meta-regression and subgroup analysis found no significant difference (P = 0.81) across ages but revealed a significantly higher prevalence in older compared to young adults (2.87% vs. 0.67%, P = 0.01). Prevalence rates were markedly higher in patients with genetic syndromes. MR progressed at 5.5 per 100 person-years, overall. Event rates for all-cause mortality, development of heart failure, and need for mitral valve intervention were 1.7, 1.0, and 1.2 per 100 person-years, respectively.

conclusionMVP is common, with greater prevalence in syndromes. Although more common with age, MVP is observed in infants. MVP related MR is progressive, especially in moderate MR, and there is a signal of excess mortality for unclear reasons. Valve services must manage the whole life journey and the potential risks associated with MVP.
