Table 2. GP participant sex and age distributions and group-specific likelihoods for tennis elbow (TE) problem at encounter (April 2000 –March 2015).

Sex	Number of GPs who managed at least one TE problem at any of the 100 encounters	% sex distribution of these GPs	^GP sex-specific likelihood (%) of managing TE at any of the 100 encounters (95% CI)^
Male^	1,824	68.7	19.8 (19.0–20.6)
Female	830	31.3	15.1 (14.2–16.1)
All known sex	2,654	100.0
Age group (years)*	Number of GPs who managed at least one TE problem at any of the 100 encounters	% age distribution of these GPs	GP age-specific likelihood (%) of managing TE at any of the 100 encounters (95% CI)^
<35 years	158	6.0	16.2 (13.9–18.5)
35–44 years	612	23.2	19.3 (17.9–20.7)
45–54 years	945	35.8	18.9 (17.8–20.0)
55+ years	922	35.0	16.8 (15.8–17.8)
All known age	2,637	100.0

*Missing: Of 14,716 GP participants in total, GP age was missing for 90. Of 2,654 GPs who managed at least one TE problem at any of the 100 encounters, age was missing for 17.

^Example: As an example, of 9,226 male GPs, the likelihood that TE was managed at any of the sample 100 encounters was 19.8% (95% CI: 19.0–20.6)
