Hyperparathyroidism in pregnancy.
Article in BMJ case reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
Hyperparathyroidism is a rare disease during pregnancy, which has increased risks, including miscarriage and fetal growth restriction. However, the diagnosis of hyperparathyroidism is frequently not recognised or delayed as symptoms are non-specific and calcium is not routinely measured. With a thorough medical history and clinical suspicion, early diagnosis and treatment can reduce the risk of some pregnancy complications. A 35-year-old woman presented at 13/40 with hyperemesis gravidarum. She had elevated serum calcium and a parathyroid lesion on ultrasound. She underwent a parathyroidectomy with rapid normalisation of her calcium. Histopathology confirmed a parafibromin-deficient parathyroid tumour, suggestive of hyperparathyroidism jaw tumour syndrome. At 30/40, she presented with pre-eclampsia (hypertension, hyper-reflexia, proteinuria and intrauterine growth restriction) and had a caesarean section at 30+1/40, delivering a male infant, 897 g (fifth percentile). She had a prior 12-month history of chronic constipation and nephrolithiasis but was not investigated further despite elevated calcium (2.82 mmol/L).
