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

purposeSeveral countries are legalizing the use of medicinal cannabis and easing restrictions on its recreational use. While adults have been the primary target of these initiatives, expanding access to cannabis will likely lead to increased use by children. While the effects of cannabis on pediatric neuropsychological and mental health outcomes have been broadly studied, there are limited data on the physical health effects of cannabis, including endocrine health. Animal studies have shown that chronic cannabis use leads to delayed sexual maturation; however, its effects on pubertal outcomes in children are not well studied. This systematic review aimed to assess the effect of cannabis use on pubertal timing and tempo in children.

methodsWe conducted a systematic review with literature searches in MEDLINE, Embase, Cochrane Database of Systematic Reviews, Central, PsycINFO, CINAHL, Web of Science, and SPORTDiscus from inception to February 2018. A gray literature search was also completed in Clinicaltrials.gov and ProQuest Dissertations and Theses A&I. The primary outcome was pubertal timing, while secondary outcomes included pubertal tempo and final height and weight. We had no restrictions on date or language of publication of papers. Two reviewers independently assessed records for eligibility, with a third reviewer resolving disagreements.

resultsOur database and gray literature searches identified 759 records. A total of 29 full-text papers were assessed for eligibility. However, all studies were ultimately excluded as they did not meet the eligibility criteria.

conclusionOur results highlight a significant gap in existing literature regarding the effects of cannabis use on puberty. Adequately powered longitudinal studies are urgently needed to provide pediatricians and other health care providers with high-quality information on the potential effects of cannabis on the physical health of children.
