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

This study aimed to report the effects of policosanol (20 mg/day) on blood pressure values in Cuban patients with grade I hypertension. A double-blind multicenter trial randomized 400 eligible patients divided into two strata of patients with either prehypertension or grade I hypertension (200 patients each) treated with either placebo or policosanol 20 mg/day (100 patients/group/stratum) for 12 weeks. Having published the results of pre-hypertensive patients, here we report the grade I hypertension stratum (SBP 140-159 mmHg, DBP 90-99 mmHg) results. The primary outcome targeted whether policosanol could achieve significant systolic blood pressure (SBP) reductions ≥10 mmHg versus baseline and significantly different from placebo. Changes in diastolic blood pressure (DBP) and lipid profile variables were secondary outcomes. Safety indicators and adverse events were assessed. Statistical analyses were conducted by Intention to Treat. Both groups were similar at randomization. At study completion, policosanol significantly lowered (p < 0.001) SBP, the primary outcome, by more than 10 mmHg related to baseline and placebo, while also significantly decreasing (p < 0.001) DBP values versus baseline and placebo. Also, more (p < 0.001) policosanol patients reached SBP reductions ≥10 mmHg and DBP reductions ≥5 mmHg versus baseline (74% and 91%, respectively) than placebo patients (12% and 15%, respectively). Policosanol significantly lowered low-density lipoprotein-cholesterol (LDL-C) and total cholesterol, while increasing high-density lipoprotein-cholesterol (HDL-C). It is concluded that oral administration of policosanol 20 mg/day for twelve weeks significantly lowered SBP and DBP in Cuban patients with grade I hypertension, and improved lipid profile variables, being safe and well tolerated.
