Several photometric surveys for short-period transiting giant planets have targeted a number of open clusters, but no convincing detections have been made. Although each individual survey typically targeted an insufficient number of stars to expect a detection assuming the frequency of short-period giant planets found in surveys of field stars, we ask whether the lack of detections from the ensemble of open cluster surveys is inconsistent with expectations from the field planet population. We select a subset of existing transit surveys with well-defined selection criteria and quantified detection efficiencies, and statistically combine their null results to show that the upper limit on the planet fraction is 5.5% and 1.4% for 1.0 $R_{J}$ and 1.5 $R_{J}$ planets, respectively in the $3
