Factors associated with the exposure of vaccines to adverse temperature conditions: the case of North West region, Cameroon.
Article in BMC research notes, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 25 papers.
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
backgroundAdverse temperature recording in vaccine's cold chain is a major issue worldwide and this condition is known to compromise the quality of vaccines very rapidly. In Cameroon, with tropical climate, vaccines exposure to abnormal temperatures is very common. This study was conducted to identify factors associated to abnormal temperature recording in cold chain in the North West region.
resultsA total of 65 vaccinating health facilities were visited for the study from eight health districts. Concerning type of health facility, 48 (73.8%) of the health facilities were governmental facilities. About 50 (76.0%) of the facilities had a functional thermometer. Among the 50 health facilities with functional thermometer, abnormal temperatures were registered in 10 (20%) health facilities during data collection and 12 (24%) in the 2 months preceding collection. Factor significantly associated with abnormal temperature recording was the absence of an alternative power source (OR = 6.5, p = 0.03).
conclusionThe absence of an alternative source of power was significantly associated with abnormal temperature exposure in the 2 months preceding data collection. To improve on the quality of vaccines administered in North West region, each vaccinating health facility must have at least two sources of power supply.
