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

objectiveThis study aims to examine the effects of methamphetamine (MA) use and dependence and MA withdrawal symptoms on the telomere length and whether shortening of the latter is associated with MA-induced psychosis (MIP).

methodsThis study included 185 MA-abuse, 118 MA-dependent, and 67 MIP patients, diagnosed using DSM-IV criteria. The Semi-structured Assessment for Drug Dependence and Alcoholism (SSADDA) questionnaire was employed to collect MA-related data. MIP was confirmed using the Methamphetamine Experience Questionnaire (MEQ). The leukocyte telomere length was measured using real-time polymerase chain reaction measuring the Telomere/Single gene ratio (T/S ratio). Data were analysed using multivariate statistical analyses.

resultsThere were no significant associations between the T/S ratio and severity of MA-use, MIP, and MA withdrawal symptoms. MIP was significantly predicted by alcohol dependence, antisocial personality disorder, and MA-use severity. There were significantly positive associations between the T/S ratio and previous traumatic and life-threatening events. The T/S ratio was not affected by alcohol and nicotine dependence. Alcohol and nicotine dependence, antisocial personality disorder, and severity of MA use increased risk of MA withdrawal symptoms.

conclusionMIP and MA-use severity are not associated with leukocyte telomere length, but previous traumatic and life-threatening events are associated with increased telomere length.
