The below spreadsheet is the public data repository detailing each step of the study process. This repository contains five data sheets:

• Round-1: This sheet shows the process of basic information reading, including the title, authors, publication venue, library, and publication year of all the retrieved papers. Here we show whether a paper is retained for round 1 selection; if not, what criteria are applied to filter it out.

• Round-2: This sheet shows the process of skimming reading. For each paper, we indicate why or why not they are retained based on the abstract, introduction, and conclusion.

• Round-3: This sheet shows the process of intensive reading. For each paper, we indicate why or why not they are retained in the final list based on the detailed reading of the paper.

• Snowballing: This sheet includes all the papers between 2010 to 2020 retrieved from snowballing, excluding papers that are already retrieved in the initial search. For each paper, we tag why or why not each paper is retained, based on the inclusion and exclusion criteria.

• Data Annotation: This sheet contains the detailed annotation data described in Table 3 “Annotated Data Items”.
