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

Patients with osteoporosis prescribed risedronate gastro-resistant had a lower incidence of fractures versus those prescribed other oral bisphosphonates. Administration of risedronate gastric-resistant does not require fasting, and this more convenient dosing administration may explain its improved efficacy. PURPOSE: Up to half of patients do not follow complex dosing instructions of immediate-release bisphosphonates used for the prevention of osteoporotic fractures, which can result in suboptimal effectiveness. Risedronate gastro-resistant (GR) offers a more convenient dosing option by eliminating the need for fasting. This study compares fracture rates and outcomes between osteoporosis women treated with risedronate GR (GR cohort) versus other oral bisphosphonates (other cohort).

methodsClaims from women with osteoporosis in the USA were analyzed. Patients were classified into the two cohorts based on the first oral bisphosphonate observed (index date) and matched 1:1 based on patient characteristics. Patients were observed for ≥ 2 years following the index date. Fracture rates, health care resource utilization and costs, and treatment persistence were compared.

resultsIn total, 2,726 patients were selected in each cohort (median age: 60.0 years). The incidence of fractures was lower in the GR versus the other cohort for any fracture sites (incidence rate ratio, 95% CI: 0.83, 0.70-0.97) and spine fractures (0.71, 0.54-0.95), although the respective rate of medication discontinuation at 2 years was 80.5% and 74.4%. Time to first fracture was delayed for the GR cohort, reaching statistical significance after 36 months. The GR cohort incurred fewer hospitalizations (incidence rate per 1,000 patient-years: GR = 106.74; other = 124.20, p < 0.05) translating into lower hospitalization costs per patient per year (GR = $3,611; other = $4,603, p < 0.05).

conclusionsPatients prescribed risedronate GR versus other bisphosphonates had a lower incidence of fractures, which may be explained by the fact that the GR formulation is absorbed even when taken with food.
