Combination therapy of anabolic and nonbisphosphonates antiresorptive agents for the treatment of osteoporosis: A meta-analysis.
Synthesis in Medicine, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundAccording to the mechanisms of action, combination therapy of anabolic and antiresorptive agents may produce more effect for the treatment of osteoporosis. However, the combination therapy of anabolic agents and bisphosphonates reports no benefit and even reduced the anabolic effects of anabolic agents. This study aims to assess the effect of combination therapy of anabolic and nonbisphosphonates antiresorptive agents in adults with osteoporosis.
methodsMedline, EMBASE, and Cochrane Library were searched from January 1, 1980 to November 1, 2017 for randomized controlled trials (RCTs) of adults with osteoporosis treated in combination therapy of anabolic and nonbisphosphonates antiresorptive agents compared with monotherapy of either agent alone. The primary outcome was the incidence of fractures. The secondary outcomes were the bone mineral density (BMD) changes at lumbar spine and total hip. Continuous outcomes were expressed as standardized mean difference (SMD) and 95% confidence interval (CI), while dichotomous outcomes were expressed as risk ratio (RR) and 95% CI. The meta-analysis was performed using a random-effects model. I statistic (I > 50% as a threshold indicates significant heterogeneity) was used to assess the heterogeneity.
resultsA total of 10 trials with a total of 1042 patients were included. The pooled results showed that the combination therapy demonstrated a significant advantage over a monotherapy in the BMD improvement at the lumbar spine (SMD 1.18; 95% CI, 0.63 to 1.72; I = 93%) and the total hip (SMD 0.89; 95% CI, 0.48 to 1.29; I = 88%) and further reduce the fracture risk (RR, 0.45; 95%CI, 0.21 to 0.94; I = 0%).
conclusionsLow-to-moderate-quality evidence shows that the combination therapy of anabolic and nonbisphosphonates antiresorptive agents is superior to monotherapy in improving the BMD and reducing the fracture risk. However, further high methodological quality studies are needed to determine the antifracture efficacy, cost-effectiveness and safety of this strategy of combination therapy.
