Orient and Walsall shared a dour goalless draw in front of Brisbane Road's lowest league crowd of the season.
For Walsall there was the consolation that their point brought an end to a run of five successive league defeats, while for Orient it was their second clean sheet in five days.
Although Orient looked the better side in the first half they struggled to pose a threat in the final third of the pitch and had only one corner just before the break to show for their efforts.
Walsall were closest to a goal when Matt Richards' 27th-minute free-kick from wide out on the right was stabbed goalwards by defender Oliver Lancashire, who forced home keeper Jamie Jones to push the ball away for a corner.
Orient forced four corners in the opening five minutes of the second half - 11 in all - and from one, striker Alex Revell forced a fine tip-over by visiting goalkeeper Jon Brian.
Orient had far more of the second-half play, but they could not make their superiority count in front of a crowd of 2,963.
