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

purposeThere is contradictory evidence related to the impact of ultra-marathon running on right ventricular (RV) structure and function. Consequently, the aims of this study were to: (1) comprehensively assess RV structure and function before and immediately following a 100-mile ultra-marathon in highly trained runners, (2) determine the nature of RV recovery 6 h post-race, and (3) document 12-lead electrocardiogram (ECG) changes post-exercise.

methodsEchocardiography and 12-lead ECG were assessed in 15 competitors in a repeated measures design before and immediately after completion of the 2013 Western States Endurance Race. A subset of nine was reassessed 6 h into recovery. Standard echocardiography was used to determine RV size, function and wall stress. Myocardial speckle tracking (MST) provided peak, time to peak and temporal indices for RV longitudinal strain and strain rates (ε and SR).

resultsRV size was increased post-race (inflow tract 14 %, outflow tract 11 %, P = 0.004 and 0.002). RV wall stress was elevated by 11 % post-race. Peak RV ε was reduced by 10 % (P = 0.007) and significantly delayed post-race (P = 0.008). Most changes in RV function persisted at the 6-h assessment. Post-race there was an increase in the prevalence of right-sided ECG changes.

conclusionsCompletion of a 100-mile ultra-marathon resulted in acute changes in RV structure and function that persisted 6 h into recovery and are consistent with sustained exposure to an elevated RV wall stress. These findings were supported by right-sided changes to the 12-lead ECG.
