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

backgroundThis study aimed to evaluate the role of two-dimensional speckle-tracking imaging (2D-STI) and myocardial layer-specific analysis in evaluating early left ventricular (LV) myocardial function and systolic dyssynchrony in young and middle-aged uremic patients undergoing peritoneal dialysis (PD).

methodsWe enrolled 31 PD patients aged ≤65 years with preserved LV ejection fraction (LVEF, ≥54%) as the PD group and 49 age-matched healthy people as the control group. Echocardiography was used to assess the left atrial diameter index (LADI, LAD/BSA), LV mass index (LVMI), LVEF, peak early diastolic velocity/late diastolic velocity (E/A) (measured by pulsed Doppler), and peak early diastolic velocity (by pulsed Doppler)/peak velocity of the early diastolic wave (by pulsed-wave tissue Doppler) (E/e'). Next, we used 2D-STI and myocardial layer-specific analysis to obtain longitudinal strains (LS) of the endocardium (LSendo), the myocardium (LSmyo), the epicardium (LSepi), and the global myocardium (GLS). Then, we measured the postsystolic index (PSI) to evaluate LV myocardial function. Time to peak LS (TTP) and peak strain dispersion (PSD) from 17 consecutive segments were assessed to quantify LV dyssynchrony.

resultsCompared with the controls, PD patients had significantly increased LADI (p = 0.041), LVMI (p = 0.000), and E/e' (p = 0.009), but reduced LVEF (p = 0.000) and E/A (p = 0.000). The average values of GLS (GLS avg) (p = 0.01) and GLS of the apical 2-chamber view (p = 0.003), including the LSendo (p = 0.024), LSmyo (p = 0.024), and LSepi (p = 0.032), were significantly decreased in patients with PD compared with controls. In PSI, segments of LS were markedly delayed in the anterior septum (p = 0.047), anterior (p = 0.000) and septum wall (p = 0.024) from basal segments, anterior wall (p = 0.001) from middle segments, and anterior (p = 0.024) and inferior (p = 0.024) wall from apical segments. Moreover, PSD was significantly increased in PD patients (p = 0.015), while TTP was evidently delayed in the anterior septum (p = 0.004), anterior (p = 0.000) and posterior (p = 0.042) wall from basal segments, and inferior wall (p = 0.048) from apical segments.

conclusionsDespite preserved LVEF, young and middle-aged PD patients developed LV dysfunction and myocardial systolic dyssynchrony earlier compared with controls.
