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

Objective Sacubitril/valsartan combines the effects of angiotensin receptor blockers (ARBs) with increased atrial natriuretic peptide (ANP) levels through neprilysin inhibition. ANP has vasodilatory and natriuretic effects. ARB efficacy is diminished by high daily salt intake (HDSI) in hypertension; however, it is unclear whether HDSI similarly affects the efficacy of sacubitril/valsartan. We aimed to assess the effect of ANP on blood pressure (BP) in patients with hypertension and HDSI treated with sacubitril/valsartan. Methods Fifty consecutive patients with hypertension previously on ARBs were enrolled and switched to sacubitril/valsartan (200 mg). BP and ANP levels were measured at baseline and two weeks after initiation. DSI was calculated from spot urine samples at these time points. Patients were divided into HDSI and low DSI (LDSI) groups based on the median baseline DSI. Results All patients had chronic kidney disease. The baseline average systolic/diastolic BP was 151±11/89±16 mmHg. At follow-up, both groups showed significant absolute and percentage BP reductions, with no significant differences between the groups. The DSI levels obtained by urine tests were significantly higher in the HDSI group than in the LDSI group. ANP levels increased in both groups at follow-up and more significantly in the HDSI group than in the LDSI group (573±585 vs. 84±78 pg/mL, p<0.001; 144±98% vs. 35±28%, p<0.001). Conclusion Sacubitril/valsartan was effective in lowering BP not only in patients with lower salt intake but also in patients with higher salt intake. The notable medication-induced increase in ANP levels may contribute to BP reduction through vasodilatory and natriuretic actions.
