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

purpose of reviewWe summarize and discuss evidence on management of chronic hypoparathyroidism (HypoPT) and primary hyperparathyroidism (PHPT) in pregnancy and lactation to provide guidance for clinical care. RECENT

findingsWomen with HypoPT are at increased risk of certain pregnancy complications, though most pregnancies are uncomplicated. Conventional therapy with activated vitamin D and calcium is continued throughout pregnancy, but there are unpredictable changes in the required dosages warranting regular surveillance during pregnancy (e.g., all 3 to 4 weeks). Data on parathyroid hormone (PTH) replacement therapy in pregnancy are limited, but a few case reports suggest favourable outcomes with this treatment. During lactation, dosage requirements for conventional therapy of HypoPT are often reduced and usually normalize again after weaning. In women with PHPT, surgical treatment should be pursued before conception. PHPT is not associated with adverse pregnancy outcomes in women with mild hypercalcemia but maternal and fetal complications significantly increase with higher calcium concentrations. There is no clear threshold for this risk increase, but several studies and expert groups support a cut-off concentration of about 2.85 mmol/L in albumin-adjusted calcium and 1.45 mmol/L in ionized calcium. For pregnant women with PHPT and calcium above these cut-off concentrations, parathyroidectomy, preferentially in the second trimester, is recommended. Medical treatment for hypercalcaemic PHPT is limited and requires individual decision making. Immediately after delivery, hypercalcemia may worsen in women with PHPT. Clinical care of women with HypoPT and PHPT in pregnancy and lactation requires intensive surveillance and consideration of the specific changes in bone and mineral metabolism during these times.
