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

backgroundTreatment of hypocalcemia after thyroidectomy consists of an individual substitution, prophylaxis or a daily administration of calcium/vitamin D3.

objectiveDoes prophylactic therapy combined with a risk-adapted substitution of calcium and vitamin D3 reduce symptomatic hypocalcemia compared to individual substitution? MATERIAL AND

methodsAfter implementation of a new algorithm, patient data were prospectively documented and analyzed compared to a historical patient population. The algorithm consisted of a single prophylactic i. v. administration of calcium (1 g calcium gluconate 10% in 250 ml saline) and a risk-adapted oral administration of calcium and vitamin D3 after surgery. Patients without risk (parathyroid hormone, PTH > 15 pg/ml) were not treated. Patients with a low risk (PTH ≥ 6 ≤ 15 pg/ml and Ca > 2.0 mmol/l) received 3 g calcium, patients with a high risk (PTH ≥ 6 ≤ 15 pg/ml and Ca < 2.0 mmol/l) received 3 g calcium and 2 × 0.5 µg vitamin D3 and patients with a very high risk (PTH < 6 pg/ml) got 4 g calcium and 2 × 0.5 µg vitamin D3.

resultsIn this study 415 patients were included (230 prospectively and 185 retrospectively). Serum calcium of patients with individual substitution increased significantly at day 1 (p = 0.0001) and the number of patients with critical hypocalcemia (Ca < 2.0 mmol/l) decreased by half (27% vs. 12.2%; p = 0.0001). There was a significantly lower rate of symptomatic patients (24.9% vs 13.0%; p = 0.002) and a clear reduction of patients with a prolonged hospitalization (10.8% vs. 6.5%; p = 0.08). The rate of permanent hypocalcemia was comparable (2.2% vs. 2.1%). In the risk groups there was a significantly different rate of hypocalcemia: patients without risk (n = 170) in 2.2%, patients with low risk (n = 36) in 25%, patients with high risk (n = 13) in 69.2% and patients with very high risk (n = 11) in 71%.

conclusionThis new treatment regimen is practicable, significantly lowers the symptoms, also in comparison to the literature and shows a clear differentiation between the risk groups.
