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

Nowadays, connected health care applications are used more and more in the world. Service through the applications can save the patients' time and expense, such as telecare medical information system (TMIS) and integrated electronic patient record (EPR) information system. In the applications, preserving patients' privacy, transmitting messages securely and keeping mutual authentication should all be paid attention. Many authentication schemes have been proposed to make a secure communicating environment. Recently Xie et al. showed that Wen's scheme was insecure because it was under the off-line password guessing attack and without user anonymity and forward security. They gave a new three-factor authentication scheme and claimed that it was secure. However, we find that Xie et al's scheme is vulnerable to the De-synchronization attack and the server has too much storage burden in the scheme. Then we present an improved scheme which overcomes the usual weaknesses and keeps ordinary security characters. Compared with recent schemes of the same kind, our scheme is secure and practical.
