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

backgroundSitagliptin, the first of a new class of dipeptidyl peptidase-4 (DPP-4)-inhibitory oral antihyperglycemic drugs (OHDs), was introduced in Japan in December 2009. In April 2010 a safety alert was issued regarding the risk of serious hypoglycemic events when the drug is used in combination with high-dose sulfonylureas (SUs).

objectiveTo investigate trends in prescription of OHDs before and after the launch of sitagliptin, and before and after the safety alert, in order to evaluate changes in the prescribing behavior of various groups of physicians in response to the safety alert.

settingJapan.

methodPrescription data from 6,500 institutions, randomly collected from 300 Japanese pharmacies were used. A cohort of 87,678 patients with 813,374 prescriptions for OHDs, among which 464,079 included SUs (glimepiride: 317,423), was collected from August 2009 to 31 December 2010. Logistic regression analysis was conducted.

main outcome measurePrescription trends for sitagliptin and SUs, stratified by age, gender, types of prescribers and institutions.

resultsThe safety alert recommending a reduction of SU dosing was well reflected in prescriptions issued after the alert (glimepiride dose reduction from 2.78 ± 1.86 mg to 2.32 ± 1.68), especially in prescriptions issued by diabetes specialists (from 2.27 ± 1.81 mg to 1.87 ± 1.47 mg). The dose of background SUs in patients who started sitagliptin early was higher (before alert: 2.70 ± 1.80 mg, after alert: 2.51 ± 1.74 mg) than in patients without experience of sitagliptin (2.12 ± 1.57 mg). This may indicate that patients receiving high-dose SUs were selected for sitagliptin, and this might be a factor in the high frequency of hypoglycemia in the early launch phase of sitagliptin.

conclusionThe sitagliptin safety alert had a clear impact on prescribing behavior, but the impact appeared to depend on prescribers' backgrounds. Our findings should be helpful for developing a safer drug launching strategy for new classes of drugs in established categories.
