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

This paper responds to the fact that over 200 Alzheimer's disease (AD) drug candidates have failed to date and draws on searches of the literature for studies of error effects in drug developments and the authors' published works. In the same period, basic knowledge of AD pathology has greatly expanded providing both potential therapeutic targets and rationales for modifications in strategies for testing AD drug candidates. Current opinion generally holds that AD drug candidates have failed because they address pathology that is already too advanced. Less attention is paid to numerous reported methodological weaknesses capable of biasing AD clinical trials and drug developments and thus invalidating conclusions to be reached about the drugs being tested. The costs of quality controls possibly needed to better insure validity in AD drug developments raises concerns that progress toward success in AD drug development may be hindered by the costs of intervening against current methodological barriers to the successful completions of AD drug developments.
