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
aimsIn this paper, we have reported a previously undescribed risk factor of deterioration of renal function in zoledronic acid treatment of skeletal metastasis - high serum calcium level. Based on this consideration, a modified method of treatment of hypercalcemia (HCM) with zoledronic acid is suggested in this paper. MATERIAL AND
methodsBone scan findings of 1090 cancer patients were analyzed, of which 26 had intense renal parenchymal uptake as a result of HCM or bone metastases. Subsequently, a total of 56 bone metastases patients with zoledronic acid treatment were divided into three groups: HCM group who were pre-treated to normal serum calcium level (13 patients), HCM group (19 patients), and normal serum calcium group (24 patients).
resultsMore patients with intense renal parenchymal uptake were hyperglycemic, statistically significantly (18/26 versus 19/1064, P = 2.1, E-78). No more patients with intense renal parenchymal uptake were associated with bone metastases (14/26 versus 438/1064, P = 0.20). Subsequently, more HCM patients receiving zoledronic acid treatment showed renal injury compared to patients with normal serum calcium level (5/15 versus 2/24, P < 0.05) and HCM patients with pre-treatment to normal serum calcium level (5/15 versus 1/17, P < 0.05).
conclusionsIntense renal parenchymal uptake of bisphosphonates is closely related to HCM rather than to bone metastases in cancer patients. The serum calcium should be measured and reduced to normal level before zoledronic acid is used in managements of adverse skeletal events in order to decrease the risk of renal injury.
