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

Allometric principles have been applied to scale and predict human pharmacokinetic parameters of irbesartan, an important AT1 receptor antagonist. The preclinical data gathered from rats, macaques (monkeys) and dogs were used in the allometric analysis. The use of these species was rationalized because preclinical models based on these species have been used in the evaluation pharmacodynamic activity of irbesartan. The human parameter values for clearance (CL/F), volume of distribution (V/F), and elimination rate constant (Kel) were scaled using simple allometry (CL/F, V/F and Kel) or with correction factors (CL/F). The predictions of both CL/F and elimination half life (T1/2) (using Kel) for irbesartan appeared to be in close proximity to the respective human reported values (CL/F: predicted=18 L/h, observed=22.2 L/h; T1/2: predicted = 9 h; observed = 10-20 h); while, V/F value was marginally over predicted by 1.75-fold using simple allometry (predicted = 456 L; observed = 260 L). The present work presents an opportunity for prospective allometric scaling for the compounds belonging to this important therapeutic class.
