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

purposeLeft ventricular (LV) contractile reserve is commonly used for LV systolic function assessment, while data on normal LV contractile reserve to exercise and the effect of gender on it are contradictory and limited, especially in Chinese adults. The aims of the present study are to clarify echocardiographic normal reference of LV contractile reserve during treadmill exercise stress echocardiography in healthy Chinese adults and to evaluate the sex-specific impact on it. PATIENTS AND

methodsThe study population consisted of 157 healthy Chinese adults. All subjects underwent comprehensive echocardiographic assessment at rest and immediately after a symptom-limited treadmill stress test. The impact of gender on LV contractile reserve was analyzed.

resultsThe study population consisted of 157 healthy Chinese adults. All subjects underwent comprehensive echocardiographic assessment at rest and immediately after a symptom-limited treadmill stress test. The impact of gender on LV contractile reserve was analyzed.

conclusionTraditional LV contractile reserve of men was much higher than that of women in a healthy Chinese population. The difference might be because of higher BSA in men. ΔGLS was less influenced by METs and CI at rest compared to ΔEF. ΔGLS, and especially the ΔGLS index, might be considered as a more preferable contractile reserve parameter for clinical cardiac function evaluation.
