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

The study investigated the knockdown and repellent efficacy of smoke from native plants, Vitex payos (Lour.) Merr., Peltophorum africanum Sond., and Adansonia digitata L., against malaria vectors in Bare ward, Mazowe district, Zimbabwe. Three to five-day-old An. gambiae sensu lato (s.l.) were exposed to smoke from the three plants over 150 minutes during knockdown tests. Mortality was scored after 24 hours. A randomized 4 x 4 Latin square design was used to assign plant smoke and control treatments to huts and nights during repellency tests. Repellency was estimated as percentage reduction in biting using CDC light traps between 1800 and 2200 hours. Burning charcoal without plant material was used as control. SPSS software was used for data analysis. KdT50 and kdT90 rates were determined using probit analysis. A negative binomial GLM with a log link function and an emmeans post-hoc test was used to model the number of An. funestus s.l. caught based on smoke treatment, night and hut. Vitex payos and P. africanum knocked down 100% of the An. gambiae s.l. within the 150-minute exposure period. The kdT50 and kdT90 rates were more rapid for V. payos (37.8 and 69.7 min) and P. africanum (44.8 and 89.7 min) than for A. digitata (77.8 and 146.9 min). The percent 24-hr mortality was 91.7 (V. payos), 80 (P. africanum) and 71.6 (A. digitata). Smoke from V. payos (86%, p = 0.008) and P. africanum (73%, p = 0.028) significantly reduced An. funestus s.l. biting. Smoke from V. payos and P. africanum merits further investigation since it has the potential to provide an additive benefit to ITNs by targeting proportions of malaria vectors that bite before bedtime. Studies to determine whether the use of smoke from these plants has a community effect that can lead to the reduction of malaria burden are required and significant.
