Malignant and Non-Malignant Causes of Hypercalcemia: A Retrospective Study at a Tertiary Care Hospital in Pakistan.

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
backgroundHypercalcemia is a common electrolyte abnormality presenting with a variety of symptoms. The common causes are primary hyperparathyroidism and malignancy associated with hypercalcemia. However, iatrogenic hypercalcemia with the overzealous use of vitamin D has now emerged as another important cause of hypercalcemia over the past decade.
objectiveThis study aims to evaluate the causes of hypercalcemia, management strategies, and outcomes in patients admitted with hypercalcemia in a tertiary care hospital. Method: It is a retrospective study done at Aga Khan University Hospital (AKUH), Karachi after taking approval from the ethical review committee (ERC). Data were gathered about all patients admitted from 1st
resultsA total of 814 patients having hypercalcemia were included in the final analysis and their mean age was 60.8 ± 14.1 years. Male and female patients were 45.4% and 54.6%, respectively, and their mean hospital stay was 6.2 ± 5.8 days. The most common cause of hypercalcemia was malignant solid tumors (49.1%), followed by hematological malignancy (16.5%), hyperparathyroidism (10.9%), definite vitamin D toxicity (8%), chronic kidney disease (4.9%), chronic granulomatous diseases (4.7%), and probable vitamin D toxicity (3.5%). The oral cavity carcinoma (17.7%) was the most common solid tumor associated with hypercalcemia. Amongst hematological malignancy, multiple myeloma (14.4%) was the most common one. Out of 814 patients admitted with hypercalcemia, 601 (74%) patients recovered from hypercalcemia, while mortality was observed in 129 (16%) patients. Of those who expired, 110 (85.3%) had malignancy either solid tumor or hematological.
conclusionMalignancy is the most common cause of hypercalcemia in admitted patients. The knowledge of hypercalcemia's causes is of great importance so that targeted investigations can be done. Not only will it minimize the cost burden and shorten the hospitalization of patients; it will also help the physicians to decide the appropriate management accordingly. Moreover, vitamin D toxicity was also observed in a significant number of patients which highlights the common practice of using higher doses of vitamin D by physicians.
