Cameras or Divers? How Baited Remote Underwater Videos and 'Long Swims' Underwater Visual Census Complement Each Other on Coral Reefs.
Article in Ecology and evolution, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
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
Conventional methods for surveying coral reefs, such as underwater visual census (UVC), often underestimate large-bodied, mobile, or cryptic fish species due to limitations in diver mobility and visual detection. To address these limitations, rapid timed 'Long Swim' (LS) UVC protocols have been developed to better capture large predator assemblages, yet their performance relative to baited remote underwater videos (BRUV) remains poorly evaluated in topographically complex oceanic reef environments. This study provides the first site-specific comparison of BRUVS and LS-UVC protocols for predatory reef fish from nine selected families on the reefs of Pemba Island, Tanzania. To ensure robustness, we implemented post hoc spatial filtering, a multivariate sensitivity analysis excluding bait-attracted Carangidae, and site-level depth- and effort-matched bootstrap resampling. Community composition differed significantly between methods (PERMANOVA
