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

Calcium (Ca) supplements have positive effects in growing children, reduce bone loss in late-postmenopausal women with a low calcium diet and, in association with vitamin D3 supplements, may reduce non-vertebral fracture rates in elderly women. However, for many formulated pharmaceutical products their relative beneficial effects have not been conclusively established. We have compared the acute (6 h) metabolic responses following oral administration of two preparations of calcium gluconolactate and carbonate (CG and CG'), tricalcium phosphate (TCP) and calcium citrate (CC), given on separate occasions in each of 10 healthy young male volunteers. The subjects fasted overnight for 12 h and continued to fast during the experimental procedure. A 1000 mg dose of each Ca salt was ingested at weekly intervals. Blood was drawn after 30, 60, 90, 120, 180, 240, 300 and 360 min for measurement of serum Ca, phosphorus (P), parathyroid hormone (PTH) and whole plasma calcitonin (iCT). All Ca supplements induced significant (+6.4% to +8.1%; p < 0.01) increases in Ca and significant suppression of PTH (-37.4% to -57.4%; p < 0.01). Comparison of response curves revealed significantly (p < 0.01) more marked Ca increase and PTH suppression with CC than with the other three Ca salts. CG' and CC induced marginal decreases in serum P and the overall curve of P variations was different for TCP compared with CG, CG' and CC. No significant variation of iCT was recorded during the test.(ABSTRACT TRUNCATED AT 250 WORDS)
