Predictors of achievement in 48 patients with shunts

With predictor
% Achievers
Without predictor
% Achievers
Odds ratio (95% CI)
No revision of shunt (n=16)69 (11/16)28 (9/32)5.6 (1.5 to 20.1)5-160
No episodes of raised intracranial pressure (n=23)61 (14/23)24 (6/25)4.9 (1.4 to 17.0)5-160
No cranial visual defects (n=16)63 (10/16)31 (10/32)2.0 (.5 to 7.4)5-150
IQ⩾80 (n=31)55 (17/31)18 (3/17)5.7 (1.3 to 23.8)5-150
Community walker (n=11)73 (8/11)32 (12/37)5.5 (1.2 to 24.8)5-150
Mild or moderate disability (n=27)56 (15/27)24 (5/21)4.0 (1.1 to 14.1)5-150
  • 5-150 p<0.05;

  • 5-160 p<0.01

  • Multiple logistic regression analysis showed that shunt history and IQ were independent predictors of achievement.
