Table 3 Extracted variables
Variable | Description |
|---|---|
Experimental design | Description of the experimental design: Control-Exposure (CE), Before-After exposure (BA), Before-After-Control-Exposure (BACE) |
Taxon | Name of the taxon (coded from the systematic map) |
Population | Description of the exposed population (e.g. coral nubbin with length, larva with age, egg-sperm bundle) |
Life stage | Developmental stage of the exposed population (adult, juvenile, larva, gamete) |
Control | Description of the control |
Solvent | Description of the solvent and concentration used if any |
Exposure | Exposure coded from the systematic map with a more complete description if necessary |
Nominal concentration | Nominal concentration with unit |
Effective concentration | Concentration(s) actually measured with unit and time of measurement (e.g. at the beginning and/or the end of the experiment) |
Duration | Duration of exposure with unit. If several durations are available for one given exposure concentration in a test, the longest duration was extracted |
Type of system | The type of experimental system (e.g. petri dish, beaker, tank, microcosm, mesocosm, in situ) |
Temperature | Mean seawater temperature during exposure in °C |
pH | Mean seawater pH during exposure |
Measured outcome | Outcome coded from the systematic map with a more complete description if necessary. Detail was provided here in case the outcome was measured on a different developmental stage than the one exposed |
Time after exposure | Time when the outcome was measured after exposure ceased |
Quantitative result (Extraction only for the outcomes related to coral mortality, growth, settlement, symbiont density and photosynthesis) | Sample size, mean, type and measure of variation of the mean (e.g. standard deviation) for the control and the exposed group |
Narrative result (Extraction only for the exposure categories Detergent, Dispersant, Microplastic, Nanoparticle, Pharmaceutical, UV filter, and Other, and only for the outcomes that did not undergo extraction of quantitative results) | Description of a statistically tested result |
