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

In a multicenter, randomized trial, we investigated whether the long half-time dihydropyridine calcium channel blocker amlodipine was more efficacious than the gastrointestinal therapeutic system (GITS) formulation of nifedipine in lowering ambulatory blood pressure (BP) in sustained hypertension (clinic systolic/diastolic BP 140-179/90-109 mm Hg and 24-hour systolic/diastolic BP ≥ 130/80 mm Hg). Eligible patients were randomly assigned to amlodipine 5-10 mg/day or nifedipine-GITS 30-60 mg/day. Ambulatory BP monitoring was performed for 24 hours at baseline and 4-week treatment and for 48 hours at 8-week treatment with a dose of medication missed on the second day. After 8-week treatment, BP was similarly reduced in the amlodipine (n = 257) and nifedipine-GITS groups (n = 248) for both clinic and ambulatory (24-hour systolic/diastolic BP 10.3/6.5 vs 10.9/6.3 mm Hg, P ≥ 0.24) measurements. However, after missing a dose of medication, ambulatory BP reductions were greater in the amlodipine than nifedipine-GITS group, with a significant (P ≤ 0.04) between-group difference in 24-hour (-1.2 mm Hg) and daytime diastolic BP (-1.5 mm Hg). In conclusion, amlodipine and nifedipine-GITS were efficacious in reducing 24-hour BP. When a dose of medication was missed, amlodipine became more efficacious than nifedipine-GITS.
