Kalmar moved to the top of the table courtesy of a 2-1 victory at Trelleborg.
Ricardo Santos opened the scoring for the visitors in the 18th minute and Abiola Dauda struck the all-important second just before the hour, seven minutes after Andreas Whilborg had restored parity for the hosts.
The other match in the Swedish top flight today involved fourth-placed Elfsborg battling to a 2-2 draw with GAIS.
The home team were twice in the ascendancy, first through Anders Svensson five minutes before half-time and then through substitute Amadou Jawo in the 85th minute.
But on both occasions their advantage was quickly snuffed out, with Carneiro Wanderson making it 1-1 two minutes before the break and Eyjolfur Hedinsson nicking a point on the stroke of full-time.
