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.
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
objectiveMany trials confirmed the role of sacubitril-valsartan in the treatment of patients with heart failure with reduced ejection fraction (HFrEF). However, there is no sufficient data to register the effect of compulsory discontinuation of sacubitril-valsartan, either because of finan-cial shortage or adverse effects, and shifting to the standard therapy, including angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB).
methodsThe patients with HFrEF (LVEF ≤35%) were included in the study. They received treatment with sacubitril-valsartan as a replacement for an ACEI or ARB. The patients were divided into two groups: the compliant group (n=111). The non-compliant group (n=82), whose members discontinued sacubitril-valsartan after ≥5 months but <6 months since their enrollment in the study.
resultsInitially, 199 patients with HFrEF were included in the study. All the patients were started treatment with sacubitril-valsartan in addition to the evidence-based standard therapy of heart failure. Six patients were excluded at the first follow-up visit (at 6 months). The remaining 193 patients showed initial improvement of the New York Heart Association (NYHA) class, the end-diastolic volume (EDV), and the left ventricular ejection fraction (LVEF). Five patients were excluded at the 12 months' follow-up visit. The other 188 patients were divided into two groups: Group I (n=108) patients were compliant on sacubitril-valsartan for 12 months; Group II (n=80) patients were compliant on sacubitril-valsartan for ≥5 months, but stopped it at <6 months, and were shifted to ACEI or evidence-based ARB. Group II (n=80) patients showed worsening of their NYHA class, compared to the 6 months' follow-up visit (p=0.001). LVEF and EDV were also shown to be worsened in these patients when we compared them to the values of the 6 months' follow-up appointment with p=0.001 for both parameters.
conclusionThe discontinuation of sacubitril-valsartan in patients with HFrEF leads to deterioration of the LVEF as well as worsening of the functional class. The decline in LVEF and NYHA functional class occurs despite being compliant with the optimal conventional therapy with ACEI or evidence-based ARB.
