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

backgroundThe unavailability of Internet pharmacy websites may impact a consumer's drug purchases and health care.

objectiveTo address the issue of attrition, a defined set of Canadian Internet pharmacy websites was examined at three separate time intervals.

methodsIn February to March 2006, 117 distinct, fully functional "Canadian Internet pharmacy" websites were located using the advanced search options of Google and the uniform resource locator (URL) for each website was recorded. To determine website attrition, each of the 117 websites obtained and recorded from the previous study was revisited at two later periods of time within a 4-year period.

resultsAfter approximately 4 years and 5 months, only 59 (50.4%) sites were found in the original state. Thirty-four sites (29.1%) had moved to a new URL address and were not functioning as the original Internet pharmacy. For 24 sites (20.5%) the viewer was redirected to another Canadian Internet pharmacy site.

conclusionOf concern for patients if Internet pharmacy sites were suddenly inaccessible would be the disruption of continuity of care.
