1  ATLAS 2022 report combined results (see their Extended Data Table 1) using up to 139 fb${}^{-1}$ of data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV, assuming ${\mathit m}_{{{\mathit H}}}$ = 125.09 GeV.
2  All modifiers($\kappa $) $>$ 0, and $\kappa _{c}$ = $\kappa _{t}$ ( ${{\mathit B}}$ $_{inv}$ = ${{\mathit B}}$ $_{undetected}$ = 0) are assumed. Only SM particles assume to contribute to the loop-induced processes.See their Fig. 5, which shows both $\kappa _{c}$ = $\kappa _{t}$ and$\kappa _{c}$ floating.
3  ${{\mathit B}}$ $_{inv}$ = ${{\mathit B}}$ $_{undetected}$ = 0 is assumed. Coupling strength modifiers including effective photon, ${{\mathit Z}}{{\mathit \gamma}}$ and gluon are measured. See their Fig. 6.
4  ${{\mathit B}}$ $_{inv}$ floating, ${{\mathit B}}$ $_{undetected}{}\geq{}$ 0, and $\kappa _{V}{}\leq{}$ 1 are assumed. Coupling strength modifiers including effective photon, ${{\mathit Z}}{{\mathit \gamma}}$ and gluon are measured. See their Fig. 6.
5  CMS 2022 report combined results (see their Extended Data Table 2) using up to 138 fb${}^{-1}$ of data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV, assuming ${\mathit m}_{{{\mathit H}}}$ = 125.38 GeV.
6  Only SM particles assume to contribute to the loop-induced processes. See their Fig. 3 right.
7  Coupling strength modifiers including effective photon, ${{\mathit Z}}{{\mathit \gamma}}$ and gluon are measured. See their Fig. 4 left.
8  SIRUNYAN 2021R constrain the ratio of the top quark Yukawa coupling ${{\mathit y}_{{t}}}$ to its Standard Model value from ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit H}}$ and ${{\mathit t}}{{\mathit H}}$ production rates using 137 fb${}^{-1}$ ${{\mathit p}}{{\mathit p}}$ collision data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. Assuming a SM Higgs couplings to $\tau $'s, the joint interval $-0.9$ $<$ ${{\mathit \kappa}_{{t}}}(={{\mathit y}_{{t}}}/{{\mathit y}_{{t}}^{SM}}$) $<$ $-0.7$ and 0.7 $<$ ${{\mathit \kappa}_{{t}}}$ $<$ 1.1 is obtained at 95$\%$ CL (see their Fig. 17).
9  SIRUNYAN 2020C search for the production of four top quarks with same-sign and multilepton final states with 137 fb${}^{-1}$ ${{\mathit p}}{{\mathit p}}$ collision data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The results constraint the ratio of the top quark Yukawa coupling ${{\mathit y}_{{t}}}$ to its Standard Model value by comparing to the central value of a theoretical prediction (see their Refs. [1-2]), yielding $\vert {{\mathit y}_{{t}}}/{{\mathit y}_{{t}}^{SM}}\vert $ $<$ 1.7 at 95$\%$ CL. See their Fig. 5.
10  SIRUNYAN 2019BY measure the top quark Yukawa coupling from ${{\mathit t}}{{\overline{\mathit t}}}$ kinematic distributions, the invariant mass of the top quark pair and the rapidity difference between ${{\mathit t}}$ and ${{\overline{\mathit t}}}$, in the ${{\mathit \ell}}$+jets final state with 35.8 fb${}^{-1}$ ${{\mathit p}}{{\mathit p}}$ collision data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The results constraint the ratio of the top quark Yukawa coupling to its the Standard Model to be $1.07$ ${}^{+0.34}_{-0.43}$ with an upper limit of 1.67 at 95$\%$ CL (see their Table III).
11  SIRUNYAN 2018BU search for the production of four top quarks with same-sign and multilepton final states with 35.9 fb${}^{-1}$ ${{\mathit p}}{{\mathit p}}$ collision data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV. The results constraint the ratio of the top quark Yukawa coupling ${{\mathit y}_{{t}}}$ to its the Standard Model by comparing to the central value of a theoretical prediction (see their Ref. [16]), yielding $\vert {{\mathit y}_{{t}}}/{{\mathit y}_{{t}}^{SM}}\vert $ $<$ 2.1 at 95$\%$ CL.
