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.
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
backgroundUnsafe storage of unused medications at home leads to an increased risk of toxicity, accidental childhood poisoning or risk for suicide, whereas an improper disposal of unwanted/expired medications from household raises concern about environmental pollution.
objectiveThe aim of the study was to characterize expired medications collected according to the types of therapeutic groups, pharmaceutical dosage forms, expiration dates and were prescribed or over the counter drugs, and whether they came from Mexican health system or purchased by patients themselves.
settingThe study was conducted in the metropolitan area of Monterrey during a 12-month period from March 2012 to February 2013.
methodUnused/expired drugs were collected according to the collection and disposal of expired medication program instituted by the Department of Health of the State of Nuevo León. Pharmacists and students from The Autonomous University of Nuevo León recorded types of therapeutic groups, total of medicines in each group, among other classification criteria.
main outcome measureThe proportion of every collected therapeutic group, type of dosage forms, and expiration date.
resultsThe amount of medications classified was 22,140 items corresponding to a 30 % of the total collected medications in that period of time; most of them belonged to the non-steroidal anti-inflammatory drugs (16.11 %). According to the pharmaceutical dosage forms, results showed that a high percentage were solid dosage forms (73.39 %), of the total unused/expired medications, most of them were prescription drugs (91 %) which were purchased at private pharmacies. Expiration date of medications ranges from 1995 to 2016, being 2011 the outstanding year (36.66 %).
conclusionAddressing the aspect of unused drug disposition constitutes a challenge for Mexican government, due to health implications related to inadequate disposition. No matter how efficient the programs of collection and disposal of expired drugs are, none of them can collect all unused or expired drugs, that is the reason why the best approach might be to prevent this need.
