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

objectivePrimary hyperparathyroidism (PHPT) is relatively common in China and results in severe damage to the skeletal system. This study aimed to investigate changes in bone mineral density (BMD) over 2 years in patients with PHPT after parathyroidectomy.

methodsThis retrospective cohort study included patients with PHPT who underwent parathyroidectomy between January 2010 and December 2015. BMD and T-scores and Z-scores of the lumbar spine (L1, L2, L3, and L4) and total hip (femoral neck, great trochanter, and Ward's triangle) at baseline and 2 years after surgery were measured by dual-energy X-ray absorptiometry.

resultsThirty patients with moderate to severe PHPT (17 men and 13 women) aged 38.90±15.48 years were included. BMD, and T-score and Z-score values at the lumbar spine and total hip at 6 months, 1 year, and 2 years after parathyroidectomy were significantly improved compared with preoperative values. Improvement in BMD was largest at L4 (46.7%) and smallest at L1 (37.4%) in the lumbar spine 2 years after parathyroidectomy. For the total hip, the increase in BMD was largest at Ward's triangle (42.6%) and smallest at the femoral neck (37.5%).

conclusionsBMD of the lumbar spine and total hip is improved after parathyroidectomy in patients with PHPT.
