surv_ov28 {QoLMiss}

Dataset contains survival outcomes and quality of life for ovarian cancer patients

Description

Creates a dataset containing the domain-based relative hazard ratio (95 the arm-wise data from QLQ-OV28

Usage

surv_ov28(x)

Arguments

x

A data frame with ID, time, event, arm, OV_Q31,OV_Q32,...,OV_Q58 columns along with other columns if data is available.

Details

Calculates the domain-wise relative hazard ratio (95

surv_ov28 function inputs either a dataset containing missing information, represented as, 9 or 99 or NA or a data not containing any missing information. It passes the data to the ovc_qol() function, which in turn gives the domain-wise scale scores. These domain-wise scale scores are used for calculating the relative hazard ratio (95 the data arm-wise.

The surv_ov28 function includes the ovc_qol() function which will consider the arm-wise data and calculate the domain-wise scale scores. Hence, two set of domain-wise scale scores will be obtained, one for each arm.

Each of the domain-wise scales, 'Abdominal_GI','Peripheral_Neuropathy','Hormonal','Body_Image', 'Attitude_to_Disease','Chemotherapy_side_effects','Other_Single_Items','Sexuality', are considered as the covariates. Using these columns, Cox-Proportional model will be used for univariate analysis for each of the covariates. The hazard ratio (95

Thus, the output will contain three columns, Hazard Ratio(HR), Lower 95

surv_ov28(x)

1) Subject ID column should be named as 'ID'.

2) Each question column should be named as 'OV_Q31' for data from question 31,'OV_Q32' for data from question 32, and so on until 'OV_Q58' for data from question 58.

3) Data must contain columns for 'time', 'event' and 'arm'.

4) Data may contain more variables, such as, Age, Gender, etc.

x - A data frame with ID, time, event, arm, OV_Q31,OV_Q32,...,OV_Q58 columns along with other columns if data is available.

Value

A data frame containing the Hazard Ratio(HR), Lower 95
