comparative adjectives are often use to describe results. For example:
Study group A showed a much greater improvement than group B.
Table 1: Making comparative adjectives
|Type of adjective||Rule||Comparative adjective|
|One-syllable adjectives||+er||short → shorter|
|One-syllable adjectives that end: consonant + vowel + consonant||double the last consonant +er||big → bigger|
|Two syllable adjectives ending in ‘y’||remove ‘y’ +ier||easy → easier|
|Adjectives with two or more syllables||use ‘more’ before adjective||popular → more popular|
|Irregular adjectives||NO RULE||good → better
bad → worse
You may also need to use adverbs of frequency, which are listed below in order of increasing frequency:
Never > rarely > seldom > occasionally > sometimes > often > generally > usually > always.
Other common words for describing data are:
Less, fewer, more, much, many

Results: contact matrices
The contact matrices showed overall higher contacts between all age groups in every period compared to Lockdown 1, with increased clustering around the diagonal matrix elements indicating higher rates of contact between those of similar ages (Fig 6). This resulted in higher estimates of the basic reproduction number under controlled conditions (Rc). The periods with the highest Rc were between July and August 2020, which corresponds to lockdown easing and government incentives encouraging the public to dine in restaurants, where contacts particularly increased in 18 to 49 year olds and older adults (>60 year olds). As schools reopened in September 2020 following the summer vacation, an increase in contacts between children increased Rc by a factor of 3.17 (95% CI 3.06 to 3.27) relative to Lockdown 1 and 2.12 (95% CI 2.05 to 2.18) when assuming equal transmissibility in all age groups or assuming age-dependent transmissibility estimates relevant to SARS-CoV-2, respectively.
Severe restrictions remained in place over the Christmas holidays (for much of the population) and during Lockdown 3. However, because early childhood education institutions remained open during Lockdown 3, higher contact rates were reported between <4 year olds (S6 Fig). An increase in contacts between school-age children and a slight increase in contacts among adults were found during the periods when schools reopened during Lockdowns 2 and 3 (S6 Fig). This resulted in an Rc much greater than other lockdown periods, for example, during Lockdown 2, we estimated Rc to be 2.42 (95% CI 2.31 to 2.53) and 1.60 (95% CI 1.54 to 1.66) times higher than Lockdown 1, for equal and COVID-like transmissibility by age, respectively.

You may wish to read the whole of the results section of the above article here, where you will find many more phrases for describing the data.
higher contacts… compared to Lockdown 1: comparative to state that one thing was greater than another
with increased clustering: referring to an increase in the data
indicating higher rates: comparative again – more than before
an increase in contacts: referring to an increase in the data
higher contact rates: comparative again comparing now and before
a slight increase: the adjective ‘slight’ tells us that the increase was small
much greater than: ‘much greater’ tells us that the increase was big
1.60 times higher than: this gives us a numerical quantity for the difference
