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

backgroundThe transmission of malaria is known to be sensitive to the survival (longevity, mortality) of its mosquito vector, yet there have been few reviews of estimates of this important population parameter in the malaria-carrying genus Anopheles.

methodsWe carried out a systematic search for and meta-analysis of survival estimates, framed around the methods of estimation, under the major groupings of ‛vertical' (based on stable age or stage frequencies), ‛horizontal' (based on recaptures of marked and released cohorts), and ‛parasitological' (proportion of infectious mosquitoes). Because of the intricacies of the estimation process we provide an outline of these methods.

resultsBy meta-analysis we quantify the average of the distribution of daily survival [Formula: see text] for vertical (0.83, 95% CI: 0.80-0.86), horizontal (0.73, 95% CI: 0.66-0.79) and parasitological (0.92, 95% CI: 0.86-0.95) methods.

conclusionsThe meta-analysis demonstrates the anticipated result that horizontal estimates are lowest because they estimate apparent survival (survival and non-emigration) rather than true survival. On the other hand, vertical methods make strong assumptions about the stability or stationarity of the underlying populations. Further potential sources of methodological bias are mentioned. The substantial differences in estimates between methods indicates that methodological biases need to be considered when making use of available survival estimates.
