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

The absorption of (47)Ca Cl(2) taken with a milk and porridge meal was measured in normal subjects, patients with a partial gastrectomy, and patients with malabsorption. The addition of palm oil to the meal depressed calcium absorption, whereas the addition of medium-chain triglyceride had no effect. The contrasting effect of the two fats on calcium absorption was most marked in patients with a partial gastrectomy and least marked in patients with malabsorption. In patients with malabsorption, impairment of calcium absorption was most marked in the patients with a significant increase in faecal fat excretion. Absorption of calcium was greater in patients with a partial gastrectomy than in normal subjects.
