Possible improvement of survival with use of zoledronic acid in patients with bone metastases from renal cell carcinoma.

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
backgroundBisphosphonates play an indisputable role in preventing skeletal-related events (SREs) secondary to bone metastases, and also have a direct effect on tumor cells. However, it remains unclear whether bisphosphonates improve overall survival (OS) for renal cell carcinoma (RCC) patients with bone metastases.
methodsBetween 1978 and 2010, a total of 45 patients who had RCC metastatic to bone and were classified as intermediate risk according to Memorial Sloan-Kettering Cancer Center criteria were included in this retrospective study. In this cohort, 23 patients received zoledronic acid (ZOL) treatment (ZOL-treated group) whereas the other 22 did not (non-ZOL-treated group). The primary endpoint was OS and the secondary endpoint was the SRE rate defined as the total number of SREs divided by the total years under study.
resultsFor the cohort of 45 patients, the median OS from diagnosis of bone metastases was 27.2 months. Multivariate analysis showed that lower serum calcium (p = 0.0083) and ZOL treatment (p = 0.0013) were independent factors predicting longer survival. The ZOL-treated group had significantly longer OS than the non-ZOL-treated group (p = 0.0034). Patients in the ZOL-treated group experienced a lower SRE rate than patients in the non-ZOL-treated group (p = 0.0453). In particular, none of the patients in the ZOL-treated group developed spinal compression whereas 6 (28%) in the non-ZOL-treated group did (p = 0.0479).
conclusionsThe current study indicates that ZOL not only reduces SREs but possibly improves OS in these patients.
