Validation of a short questionnaire for estimating dietary calcium intakes.

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.
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
unlabelledConcern about calcium supplements, and mainly minor side effects (e.g. constipation) impacting on compliance, means that assessing dietary calcium intake is important. There is no suitable biomarker. Compared to food diaries, a short questionnaire was an efficient way of confirming that patients had adequate calcium intakes (>700 or >1,000 mg)
introductionCalcium is usually given alongside treatments for osteoporosis, but recent concerns about potential side effects have led to questioning whether supplements are always necessary. It is difficult to assess calcium intake in a clinical setting and be certain that the patient is getting enough calcium. The aim of this study was to determine whether a short questionnaire for estimating dietary calcium intakes in a clinical setting was fit for purpose.
methodsWe assessed dietary calcium intakes using a short questionnaire (CaQ) in patients attending an osteoporosis clinic (n = 117) and compared them with calcium intakes obtained from a 7-day food diary (n = 72) and a food frequency questionnaire (FFQ) (n = 33).
resultsMean (SD) daily calcium intakes from the CaQ were 836 (348) mg; from the diaries, 949 (384) mg; and from the FFQ, 1,141 (387) mg. The positive predictive value (PPV) was >80% for calcium cut-offs > 700 mg and 70% for cut-offs > 1,000 mg. The calcium intakes for the false positives results were not far below the cut-off. For 1,200 mg, the PPV was 67% or less.
conclusionThe CaQ is an adequate tool for assessing whether a patient has daily calcium intakes above 700 or 1,000 mg; if below these cut-offs, it is possible that the patient still has enough calcium in the diet, which could be clarified by questioning the patient further. As there were few patients with calcium intakes above 1,200 mg a day, the CaQ cannot be recommended as a tool for confirming higher dietary calcium intakes.
