convert_d2etasq(d, se, v, grp1n, grp2n, info = NULL, study = NULL)
``` |

`d` |
The effect size |

`se` |
The standard error of |

`v` |
The variance of |

`grp1n` |
Treatment group sample size. |

`grp2n` |
Control group sample size. |

`info` |
String with information on the transformation. Used for the print-method. Usually, this argument can be ignored |

`study` |
Optional string with the study name. Using |

The effect size `es`

, the standard error `se`

, the variance
of the effect size `var`

, the lower and upper confidence limits
`ci.lo`

and `ci.hi`

, the weight factor `w`

and the
total sample size `totaln`
