screen_analyzer: Analyze performance between the human and AI screening.

In AIscreenR: AI Screening Tools in R for Systematic Reviewing

Analyze performance between the human and AI screening.

Description

When both the human and AI title and abstract screening has been done, this function allows you to calculate performance measures of the screening, including the overall accuracy, specificity and sensitivity of the screening, as well as inter-rater reliability kappa statistics.

Usage

screen_analyzer(x, human_decision = human_code, key_result = TRUE)

Arguments

x	An object of either class'gpt' or 'chatgpt' or a dataset of either class 'gpt_tbl', 'chatgpt_tbl', or 'gpt_agg_tbl'
human_decision	Indicate the variable in the data that contains the human_decision. This variable must be numeric, containing 1 (for included references) and 0 (for excluded references) only.
key_result	Logical indicating if only the raw agreement, recall, and specificity measures should be returned. Default is TRUE.

Value

A tibble with screening performance measures. The tibble includes the following variables:

promptid	integer	indicating the prompt ID.
model	character	indicating the specific gpt-model used.
reps	integer	indicating the number of times the same question was sent to GPT server.
top_p	numeric	indicating the applied top_p.
n_screened	integer	indicating the number of screened references.
n_missing	numeric	indicating the number of missing responses.
n_refs	integer	indicating the total number of references expected to be screened for the given condition.
human_in_gpt_ex	numeric	indicating the number of references included by humans and excluded by gpt.
human_ex_gpt_in	numeric	indicating the number of references excluded by humans and included by gpt.
human_in_gpt_in	numeric	indicating the number of references included by humans and included by gpt.
human_ex_gpt_ex	numeric	indicating the number of references excluded by humans and excluded by gpt.
accuracy	numeric	indicating the overall percent disagreement between human and gpt (Gartlehner et al., 2019).
p_agreement	numeric	indicating the overall percent agreement between human and gpt.
precision	numeric	"measures the ability to include only articles that should be included" (Syriani et al., 2023).
recall	numeric	"measures the ability to include all articles that should be included" (Syriani et al., 2023).
npv	numeric	Negative predictive value (NPV) "measures the ability to exclude only articles that should be excluded" (Syriani et al., 2023).
specificity	numeric	"measures the ability to exclude all articles that should be excluded" (Syriani et al., 2023).
bacc	numeric	"capture the accuracy of deciding both inclusion and exclusion classes" (Syriani et al., 2023).
F2	numeric	F-measure that "consider the cost of getting false negatives twice as costly as getting false positives" (Syriani et al., 2023).
mcc	numeric	indicating percent agreement for excluded references (Gartlehner et al., 2019).
irr	numeric	indicating the inter-rater reliability as described in McHugh (2012).
se_irr	numeric	indicating standard error for the inter-rater reliability.
cl_irr	numeric	indicating lower confidence interval for the inter-rater reliability.
cu_irr	numeric	indicating upper confidence interval for the inter-rater reliability.
level_of_agreement	character	interpretation of the inter-rater reliability as suggested by McHugh (2012).
