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

backgroundDetermination of left ventricular hypertrophy (LVH) via electrocardiogram (ECG) is a known independent risk factor for cardiovascular morbidity and mortality in hypertension (HTN). Dietary sodium and HTN are both associated with unfavorable alterations in left ventricular mass, however, to what extent their interplay affects ECG screening for LVH is unclear.

methodsThe effects of controlled dietary sodium manipulation on ECG determinants of LVH in hypertensive subjects were evaluated using well-established voltage criteria for LVH. ECGs from 80 hypertensive subjects were evaluated following random sequence assignment to 7 days of high sodium (HS) intake (200 mEq/24 h), and then 7 days of low sodium (LS) intake (10 mEq/24 h).

resultsSodium restriction over 7 days resulted in significant decreases in overall, and LVH-specific, ECG voltages. Most subjects exhibited decrements in overall ECG voltage with sodium restriction (72%); however, a smaller subset displayed higher voltages when on LS intake (28%). The prevalence of ECG-determined LVH was significantly lowered with LS diet (HS diet 22/80 (28%) vs. LS diet 8/80 (10%), P < 0.05). Subjects exhibiting reversal of LVH status with sodium restriction were younger, demonstrated salt sensitivity of blood pressure, and lower LVH-specific ECG voltage.

conclusionsShort-term dietary sodium fluctuations can significantly alter overall ECG voltage and the prevalence of ECG-determined LVH in hypertensive individuals. Inclusion of dietary sodium assessment when screening hypertensive subjects for LVH by ECG may improve the consistency of cardiac risk assessment.
