How to align text and add vertical lines along the sides of the bars in a coord

I have the following data set:

LDP <- c(6.6, -1.5, 1.7, 90.3, -59.6, -7.1)
var = c("Time", "Age", "RADS", "False", "Biopsy", "Screening")

df <- as.data.frame(cbind(var, LDP))
df$LDP <- as.numeric(df$LDP)

LDP	var
6.6	Time
-1.5	Age
1.7	RADS
90.3	False
-59.6	biopsy
-7.1	Screening

I have created a poolar coord bar graph with the following code:

library(ggplot2)
ggplot(df,
       aes(x = var, y = LDP, fill = LDP >= 0))  
          geom_bar(stat = "identity", 
                   position = position_dodge(),
                   width = 1)  
          geom_hline(yintercept = 0, linetype = "dashed")  
          geom_text(aes(label = LDP), 
                    hjust = 0.5, 
                    vjust = 0.5, 
                    colour = "black", fontface = "bold", 
                    position = position_stack())  
          coord_polar()  
          theme_minimal()  
          labs(fill = "Status", x = "", y = "")  
          theme(axis.text.y = element_blank())

The above command resulted in the graph as shown in first image:

But I wants the text alignment and creating horizontal lines that goes along the sides of each bar exactly the same as in second image:

I would be thankful for your kind help.
